# Simple Ideal Gas Law but i keep getting it wrong

## Homework Statement

P=1.5 atm; n=2 mols, R=8.314; T=250 K; V=?

## Homework Equations

PV=nRT
i converted p into Pa and got 151987.5 Pa.

## The Attempt at a Solution

I plugged in all of the numbers and got V=0.027 L but it keeps saying my answer is wrong. It says answer for 2 sig figs. I am not sure what I am doing wrong. Help please?

your answer is in $m^{3}$. You need to convert to liters. Hint:

$$1 \, \mathrm{L} = 1 \, \mathrm{dm}^{3}$$

I think something went wrong with your conversion from m3 to liters. There are 1000 liters in a m3 (not 1 000 000 -- that would be ml per m3).

Thanks I got it right!
