For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the Atomic Mass. Multiply by one mole for units to cancel. H2O= 18.0 grams
500.0 grams H2O / (18.0 grams) = 27.8 moles H2O

∙ 9y agoWater, or H2O, has a molar mass of 18.0153 grams per mole. Using this, it can easily be calculated that 50 grams of water has 2.78 moles.
Wiki User
∙ 13y agoYou divide the weight with molecular weight of water. Water has molecular weight of 18 g/mol.
500.00g/18 g/mole = 27.78 moles
Wiki User
∙ 13y agoThere are 18 grams per mole in water. So,
500g divided by 18g/mol = 27.77778 moles of water.

What is the moles of CaC2O4 x H2O or CaC2O4 precipitated?
21
If the concentration of one material in a solution is given what additional information will be needed to find the concentration of a second material in the solution?
You need the volume of the solution and the stoiciometric coefficients. You must first find the moles of the first substance, by multiplying the molarity (M) by the volume (L). Once you have moles, you can compare the two substances by looking at the coefficients in your chemical equation. For instance, if your chemical equation is: HCl + NaOH --> H2O + NaCl you have a 1:1 ratio. Therefore the moles of HCl = the moles of NaOH however if you have 2H2O --> 2H2 + O2 the ratio of H2O to O2 is 2:1; the moles of H2O = 2 x the moles of O2
How many hydrogen atoms are in a water molecule?
2. Because it is H2O. the 2 is after the h showing how many
How many molecules are in 3.5grams of H2O?
There are 23 atoms in 6.0 g of water. Using this formula (6 g H2O)(1 mol H2O / 18 g H2O) = 1/3 mol H2O (1/3 mol H2O)(2 mol H / 1 mol H2O)(6.022 x 10^23 atoms H / 1 mol H) = 4.0 x 10 therefore 23 atoms.
