hello all. I'm trying to figure out this problem and it's bugging me because it's soooo simple yet i keep getting the wrong answer. here's the problem:(adsbygoogle = window.adsbygoogle || []).push({});

If 1.00 mol of carbon dioxide gas at 350 K is confined to a volume of 400 cubic centimeters, find the pressure of the gas using the ideal-gas equation.

Okay.. I know that the ideal gas equation will look like this if I am solving for pressure:

p = (nRT)/V

since I want pressure in pascals, then I will convert volume V to cubic meters, and for R constant I will use R = 8.3145 J/mol K

so far this is the information I have:

R = 8.3145 J/mol K

T = 350 K

n = 1.00 mol

V = 4 cubic meters

When I try and solve for pressure, I get 727.5 pascals. I did this 5 times, and I keet getting the same answer. however the book is telling me I'm wrong. Am I not understanding this correct? could this be one of those times the book is wrong? I hope someone can help!
