Question

How many grams of water vapor (H2O) are in a 10.2 liter sample at 0.98 atmospheres and 26°C? Show all work used to solve this problem

Answer 1

will give medal

Answer 2

use pV=nRT
find n (moles)

n=pV/RT

therefore 1mole of h2O is 18g
so n moles would be 18*n= x grams

you can substitute the values
remember T is in Kelvins.

Hope this helps
