## How many grams are in 2H2O?

The molar mass of hydrogen peroxide is 19.0 grams. 2H2O would be understood as 2 moles, or two molecules, or 2 equivalents of water. If in a reaction a molecule of chemical X reacts to liberate 2 molecules of water, a mole of X will yield 2 X 18.0g=36.0g of water.

What state of matter is 2H2O?

H2O is a liquid.

What is the difference between 2H2O and H2O?

Answer: h2o means 1 molecule of water with 2 hydrogen atom and one oxygen atom and 3h2o means 3 molecules of water. hopefully this will help you better!

What is the coefficient of H2O?

Because each water molecule, H2O, contains only one oxygen atom, two water molecules must form for each oxygen molecule that reacts. The coefficient 2 in front of the H2O(l ) makes this clear.
