Question

A sample of gas occupies 9.0 mL at a pressure of 500.0 mm Hg. A new volume of the same sample is at a pressure of 750.0 mm Hg.

Is the new pressure smaller or larger than the original?

Therefore, is the new volume larger or smaller than 9.0 mL?

What is this new volume?

Answer 1

Use the relatio P1V1=P2V2 ( p= pressure, v= volume)- assuming number of moles of gas and temperature are kept constant.

1.) A. Larger- pressure increases from 500mmHg to 750mmHg.

2.) B. Smaller

3.) B. 6.0mL
