How many moles and what is the mass?
How many moles is #3.02 * 10^25 # molecules of H2O? What is the mass of this number of molecules?
How many moles is
1 Answer
50.2 mols of Water
904 grams of Water
Explanation:
First off, we need to know what a mol is. A mol is an extremely large number representing how many molecules are in a substance. One mole is equivalent to
This mean there are 50.2 mols of water present.
Now we need to find the molar mass of water to calculate the mass of water. The formula for water is
Hydrogen:
Oxygen:
This means for every mol of water, it weighs 18.02 grams. Now we can calculate the mass
Now we know there is a total of 904 grams of water present.
