Question

a. How many moles of N2 are present in a 1.00 qt flask that has a pressure of 425 torr at a temperature of 35°C?

What is the mass in this na2?

Answer 1

It would be much simpler to change quart to liters first, then torr to kpa

PV=nRT

n= PV/RT Temps in Kelvins, V in liters, P in kpa

Answer 2

I did that but I keep getting the wrong answer
