the ratio of hydrogen atom to oxygen atoms in water is 2:1 if an amount of water contains 341 trillion atoms of oxygen how many hydrogen atoms are there? how would i do this?

math 
Reiny,
number of hydrogen atoms === 2x
number of oxygen atoms =====x
2x + x = 341
3x= 341
x= 113.6667 trillion
so about 114 trillion oxygen and 227 trillion hydrogen
