Solution: Which gas sample has the greatest volume at STP?a. 20g of Neb. 2g of H2c. 8g of Hed. 20 g of N2

Problem

Which gas sample has the greatest volume at STP?

a. 20g of Ne

b. 2g of H2

c. 8g of He

d. 20 g of N2

Solution

Here we are asked for the gas that has the greatest volume but the problem here is that we are only given the mass values. The condition is also stated to be at STP (Standard Temperature and Pressure). This gives us a clue that we can use 1 mole = 22.4 L. Just be careful when using these values since it is only true at STP.

Now with the given mass, we can compute for the corresponding mole values for each.
