Answer:
2.52 g of water
Explanation:
Recall that;
1 mole of water contains 6.02 * 10^23 molecules of water
x moles of water contains 8.16 * 10^22 molecules of water
x = 8.16 * 10^22 * 1/ 6.02 * 10^23
x = 1.4 * 10^-1 = 0.14 moles of water
Then;
1 mole of water = 18 g of water
0.14 moles of water = 0.14 * 18 /1 = 2.52 g of water
