Answer:

The answer to your question is 106 ml

Step-by-step explanation:

Data

Volume 1 = 100 ml

Pressure 1 = 10.5 kPa

Volume 2 = ?

Pressure 2 = 9.91 kPa

Process

To solve this problem use Boyle's law.

Pressure 1 x Volume 1 = Pressure 2 x Volume 2

-Solve for Volume 2

Volume 2 = Pressure 1 x Volume 1 / Pressure 2

-Substitution

Volume 2 = 10.5 x 100 / 9.91

-Simplification

Volume 2 = 1050 / 9.91

-Result

Volume 2 = 105.95 ml ≈ 106 ml
