pi = MRT
7.56 = M*0.08205**273 + 37)
From M, then moles = grams/molar mass
thats what i did and i got it wrong. my answer was 53.46. the study guide says 54.2.
My answer is 53.5 grams. You have too many significant figures. The study guide must be wrong.
I got approx. 54.
Same set up. But the numbers I used were .08206 and MW = 180. and I got 54.
