In a school’s laboratory, students require 50.0 ml of 2.50 m h2so4 for an experiment, but the only available stock solution of the acid has a concentration of 18.0 m. what volume of the stock solution would they use to make the required solutiona. 0.900 ml
b. 1.11 ml
c. 6.94 ml
d. 7.20 ml

The volume of stock solution of acid required 6.94 mL.

Explanation:

To calculate the volume of stock solution, we use the equation given by neutralization reaction:

where,

are the molarity and volume of acid which is

are the molarity and volume of stock solution of acid.

We are given:

Putting values in above equation, we get:

Hence, the volume of stock solution of acid required 6.94 mL.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.
