Question

12.6g of H2C2O4. 2H20.Find the no. of molecules of H20​

Answer 1

Answer:

18 g of H2O contains = 6.022×1023 molecules. 10 g of H2O cotains =6.022×102318×10 = 3.34×1023 molecules.

Explanation:

The molar mass of the water molecule is 18 g/mol. It implies that 1 mol of water molecules weigh 18 g. 18 g of water contains 1 mol of water molecules. or 18 g of water contains 6.022 x 10^23 water molecules.
