Reptile [31]

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

VladimirAG [237]

Answer:

168.16.1.1 is correct.

Internet Protocol 10.10.1.1 and internet Protocol 172.30.1.1 are the private internet protocol addresses so they could not be used on the internet.

The Internet Protocol 234.1.1.1 has been used as a multicast address so they may not be used on the Internet.

The data structure used for file directory is called
Aleks04 [339]
This is a tough question. I’m not sure if I’ll get it right but I’ll try.

Data structures used for file directories typically have a hierarchical tree structure, referred to as a directory structure. The tree has a root directory, and every file in that system has a unique path.

The simplest method of implementing a directory is to use a linear list of file names with pointers to the data blocks. But another way that you can format a file directory is by using a hash table. With this method, the linear list stores the directory entries, but a hash data structure is also used. The hash table takes a value computed from the file name and return the pointer to the file name any linear list.

So I think it’s C. But I’m not 100% sure.

I hope that helps.

horrorfan [7]

Answer:

//Define class

public class Main {

 //define main method

 public static void main(String[] args)  

 {

   //declare and initialize the double type variable to 128

   double mexico = 128;

   //declare and initialize the double type variable to 323

   double us = 323;

   //declare and initialize the integer type variable to 0  

   int yr = 0;

   //set the while loop to check which is greater

   while (mexico < us)  

   {

     //increment in the variable by 1

     yr++;

     //initialize in the variables acc. to the percentage

     mexico *= 1.0101;

     us *= 0.9985;

   }

   //print the following results

   System.out.println("Population of the Mexico will be exceed the population U.S. in " + yr + " years");

   System.out.println("Population of the Mexico will be " + mexico + " million");

   System.out.println("and population of the U.S. will be " + us + " million");

 }

}

<u>Output</u>:

Population of the Mexico will be exceed the population U.S. in81 years

Population of the Mexico will be 288.88435953355025 million

and population of the U.S. will be 286.0198193927948 million

Explanation:

<u>Following are the description of the program</u>.

  • Firstly, we define the class 'Main' and inside it, we define the main method.
  • Then, declare two double data type variables which are 'mexico' and 'us' and initialize in it to 128 and 323.
  • Declare integer data type variable 'yr' and initialize in it to 0.
  • Set the while loop and pass the condition to check that the variable 'mexico' is less than the variable 'us' then, increment in the variable 'yr' by 1 and multiply the variables 'us' and 'mexico' by the following percentage.
  • Finally, print the following results with the message.
