Answer:
40.03g/mole
Explanation:
Given parameters:
Mass = 42.10 g/mole and abundance = 93.50%
Mass = 8.30 g/mole and abundance = 6.200%
Mass = 50.40 g/mole and abundace = 0.3000%
Find;
Average atomic mass = ?
Solution:
Average atomic mass = sum (mass x abundance)
Average atomic mass = (
) + (
x 8.3) + (
)
= 39.36g/mole + 0.52g/mole + 0.15g/mole
= 40.03g/mole
Answer:
An appropriate solvent is <u>only in the fingerprint region. </u>
Explanation:
For scientists to study the infrared spectra of substances in the various states of matter, solutions are usually made with solvents. However, it has been noted that some of these solvents can interfere with the reaction spectra or be absorbed within the range of the solutes. A solution to this problem is using the right solvents with non-interfering infrared spectrum and which have no chemical effect on the solute.
The bands formed by the solvent should also be located in the the fingerprint spectrum. Examples of solvents used to achieve this and which meet up these requirements include, Carbon tetrafluoride and Carbon disulfide.
Answer:
The pricing strategy is an important element in setting up the selling price of a product.
Explanation:
The pricing strategy is an important consideration while fixing up the selling price of product manufactured. When setting up a selling price of a product, the companies set up product calculation. Businesses should decide the pricing strategy before they advertise the products to the customers.
There are mainly 5 benefits to the businesses while doing a product calculation. They are:
--- Doing competition based pricing enables the company to compete with the rival companies product and is based on the market based study. Competition pricing is a useful tool for the retailers as well as the small businesses.
--- Doing a cost plus pricing helps the total cost of making the product and also an add up in the market in order to determine the pricing of the product.
--- Dynamic pricing :
Dynamic pricing is a non static pricing. Dynamic pricing is an efficient method for the market based on the supply and demand.
--- Penetration pricing :
Penetration pricing is used by the large companies which is used to capture the market share by the setting product prices at the below market level so as to gain customers.
--- Doing a research for the price skimming helps the company to set up the accurate price for the product rather than readjusting the prices of the product later on based on the demand and the supply.
