WebThe first step is to find the molar mass of H2O (water). Add up the atomic masses of: 2 hydrogens: ~1.001 * 2 = 2.002 g/mol and 1 oxygen: ~15.999 g/mol 15.999 g/mol + 2.002 g/mol = 18.001 g/mol Next, divide 45g by the molar mass: 45 g / (18.001 g/mol) = 2.5 moles Thus, there are ~2.5 moles of water in 45g of water. 1 Asad Hussain Web23 dec. 2024 · How many atoms are in 2 moles of H2O? 2 mol H 2 O = 1 (2 x 6.02 x 10 23)= 1 (1.204 x 10 24) = 1.204 x 10 24 oxygen atoms *2 moles of water contains 1.204 x … how fast is 125cc atv
