Question

find the number of moles in 15 gms of water.​

Answer 1

Answer:

18.01528

Explanation:

The answer is 18.01528. We assume you are converting between grams Water and mole. You can view more details on each measurement unit: molecular weight of Water or mol The molecular formula for Water is H2O. The SI base unit for amount of substance is the mole.

Answer 2

Answer:

We know that 18 g of H2O contains 1 mole (or 6.022 x 10^23) molecules of water because the molar mass of H2O is 18 g/mol.

So 1 g water will contain 1/18 moles of H2O molecules.

Now 15 g of water will contain 15/18 moles of H2O.

So molecules of H2O = (15/18) x 6.022 x 10^23 = 5 x 10^23 molecules.

Hope you got it.
