# Ideal Gas law question watch

1. What is the volume occupied by 3.36 g NH3(g) when the pressure is 740 mm Hg and its temperature 27 degrees celcius?
A. 5.00 L B. 4.74 L C. 1.44x10^3 L D. 0.117 L E. 500 L
I keep getting the answer wrong
what I did is
PV=nRT
740*V=(3.36/17)*0.082*(27+273)

v= 0.00657
2. your value of R is wrong, it's 8.31
plus pressure is in Pa not mmHg-1 i don't know the conversion and/or if they are the same

Don't forget though, you volume will be in m^-3 and a litre is dm^-3 so be careful
