Question

A gas at 772 mm Hg and at 35°C occupies a volume of 6.851. Calculate its volume at STP.

Answer 1

The only time it isn't is if we are specifically told gas was added, ... V2 = 6.85L x (772 mmHg / 760mmHg) x (273.15K ... STP I could have set this up the other way.

Answer 2

Answer:

6.17 L

Explanation:

Given A gas at 772 mm Hg and at 35°C occupies a volume of 6.851. Calculate its volume at STP.

We need to find the volume at STP. So, converting we get 35 + 273 = 308 k

We know that P1V1 / T1 = P2V2 / T2

So we need to find V2

So P2 V2 T1 = P1 V1 T2

V2 = P1 V1 T2 / P2 T1

V2 = 6.851 x 772 x 273.15 / 760 x 308.

Now V2 = 1444682.7018 / 234080

So V2 = 6.17 L

Volume at STP will be 6.17 L
