Problem: A 275 mL gas sample contains argon and nitrogen at a temperature of 65 oC. The total pressure of the sample is 725 mmHg and the partial pressure of argon is 231 mmHg. What mass of nitrogen is present in the sample?

FREE Expert Solution

We are asked to calculate the mass of nitrogen is present in the sample. 


Calculate the partial pressure of nitrogen: 

PT =PAr + PN2 PN2  = PT - PAr PN2  = 725 mmHg - 231 mmHg PN2  = 494 mmHg
