Aballoon containing 0.0400 mol of a gas with a volume of 500 ml was expanded to 1.00 l. answer the questions and round answers to nearest hundredth place. which equation should you use to find the amount of gas added? what is the final number of moles?

n2 =V2n1/ V1

0.08 mol

Explanation:

Equation used to calculate the amount of gas will be

Final number of moles of gas will be 0.08 moles.

Explanation: We are given a balloon which having 0.040 mole of gas having volume 500mL is expanded to volume 1 L, to calculate the amount of gas, we use Avogadro's relation, which is:

where,

  (1 L = 1000 mL)

Putting the values in the above relation, we get the final number of moles after expansion.
