Question

What volume would 56.2 mL of gas at 820 mm of Hg occupy at 720 mm of Hg?

Answer 1

49.35 mL

Step-by-step explanation:

Given: 56.2 mL of gas

To find: volume that 56.2 mL of gas at 820 mm of Hg would occupy at 720 mm of Hg

Solution:

At 820 mm of Hg, volume of gas is 56.2 mL

At 1 mm of Hg, volume of gas is
`(56.2)/(820)`

At 720 mm of Hg, volume of gas is
`(56.2)/(820)(720)=49.35\,\,mL`
