Question

A flask contains 5.0g of neon gas at a temperature of 35°C. The pressure gauge indicates 0.37atm inside the flask. What is the volume of the neon gas

Answer 1

Answer:

The volume of the neon gas is 17.07 L.

Explanation:

The ideal gas equation describes the relationship among the four variables  P, V, T, and n. An ideal gas is a hypothetical gas whose pressure-volume-temperature  behavior can be completely accounted for by the ideal gas equation.

In order to calculate the volume, first we need to convert the grams of neon to moles:

28.18 g Ne ------ 1 mol Ne

5.0 g Ne---------- x= 0.25 mol Ne

Now, using the ideal gas equation we calculate the volume:

$pV= nRT$

$V= nRT ÷ p$

$V= (0.25 mol × 0.082 L.atm/mol.K × 308.15 K ÷ 0.37 atm$

V= 17.07 L
