Question

A gas at pressure 712 mm of Hg has volume 650 cm^3. What will be its volume at 0.8
atm?​

Answer 1

Answer:

A gas is found to have a density of #"1.80 g/L"# at #"76 cm Hg"# and #27^@ "C"#. The gas is?

1.80 g/L

at

76 cm Hg

and

27

∘

C

. The gas is?

a)Oxygen b)Carbon Dioxide c)Ammonia d)Sulphur dioxide

Explanation:

The idea here is that you need to figure out the molar mass of the gas by using its density under the given conditions for pressure and temperature.

Your tool of choice will be the ideal gas law equation
