Answer:

1.6666 g/mol = 1 \frac{2}{3} g/mol

Explanation:

Molar mass of NaOH= 23+16+1 =40g/mol

Mols in 15g = 15/40 mol

If this was dissolved in 225ml of water molarity of the solution is

\frac{15}{40} ÷ 225 x 1000 = 1.6666 g/mol = 1 \frac{2}{3} g/mol

How has the global marketplace used emerging technologies to expand businesses
madam [21]

Answer:

Information Technology (IT) has revolutionized the way organizations conduct business by enabling small and medium businesses to level the playing field with larger organizations. Small businesses use an array of technology based on everything from computer server stations to portable mobile devices to expand competitive advantages in the global economic marketplace and marketing environment. So, small & medium business organizations owners are considering implementing information technology (IT) in their planning process for streamlined integration. Thus, this process is leading to future business expansion locally as well as globally. This decision allows proprietors to create smooth business operations using the most effective information technology available. On the other hand, the Internet has further linked the overseas suppliers of goods and services and their buyers. During the e-commerce era, internet traffic is increasing day by day, and e-commerce business is in the hyper growth stage. Information technology tremendously helps to boost the expansion of the current and future of marketing environment; communication technology became faster than ever. Though, globalization creates a little challenge for multinational companies to share resources and knowledge across a number of businesses inside and outside the country. Outsourcing and freelancer ease this challenge because multinational companies recruit talent freelancers and outsource their projects to the highly expert vendors and then the works are done through the team of people very effectively and efficiently.

What is an 8086 microprocessor used for
Liula [17]
A sixteen bit microprocessor chip used in early IBM PCs. The Intel 8088 was a version with an eight-bit externaldata bus.

The Intel 8086 was based on the design of the Intel 8080 <span>and </span>Intel 8085 (it was source compatible with the 8080)with a similar register set, but was expanded to 16 bits. The Bus Interface Unit fed the instruction stream to theExecution Unit through a 6 byte prefetch queue, so fetch and execution were concurrent - a primitive form ofpipelining (8086 instructions varied from 1 to 4 bytes).

It featured four 16-bit general registers, which could also be accessed as eight 8-bit registers, and four 16-bit indexregisters (including the stack pointer). The data registers were often used implicitly by instructions, complicatingregister allocation for temporary values. It featured 64K 8-bit I/O (or 32K 16 bit) ports and fixed vectored interrupts.There were also four segment registers that could be set from index registers.

The segment registers allowed the CPU to access 1 meg of memory in an odd way. Rather than just supplyingmissing bytes, as most segmented processors, the 8086 actually shifted the segment registers left 4 bits and addedit to the address. As a result, segments overlapped, and it was possible to have two pointers with the same valuepoint to two different memory locations, or two pointers with different values pointing to the same location. Mostpeople consider this a brain damaged design.

Although this was largely acceptable for assembly language, where control of the segments was complete (it couldeven be useful then), in higher level languages it caused constant confusion (e.g. near/far pointers). Even worse, thismade expanding the address space to more than 1 meg difficult. A later version, the Intel 80386, expanded thedesign to 32 bits, and "fixed" the segmentation, but required extra modes (suppressing the new features) forcompatibility, and retains the awkward architecture. In fact, with the right assembler, code written for the 8008 canstill be run on the most <span>recent </span>Intel 486.

The Intel 80386 added new op codes in a kludgy fashion similar to the Zilog Z80 and Zilog Z280. The Intel 486added full pipelines, and clock doubling (like <span>the </span>Zilog Z280).

So why did IBM chose the 8086 series when most of the alternatives were so much better? Apparently IBM's own engineers wanted to use the Motorola 68000, and it was used later in the forgotten IBM Instruments 9000 Laboratory Computer, but IBM already had rights to manufacture the 8086, in exchange for giving Intel the rights to its bubble memory<span> designs.</span> Apparently IBM was using 8086s in the IBM Displaywriter word processor.

Other factors were the 8-bit Intel 8088 version, which could use existing Intel 8085-type components, and allowed the computer to be based on a modified 8085 design. 68000 components were not widely available, though it could useMotorola 6800 components to an <span>extent.
</span>
