Question

how many molecules of water are present in 0.01 mole

Answer 1

No of molecules of water present in 0.01 moles= 0.01* 6.022* 10^23= 6.022*10^21

Answer 2

1 mol contains 6.022 × 10^23 molecules
0.01 mol contains x molecules

x = 0.01 × 6.022 × 10^23
= 6.022 × 10^21

Number of molecules in 0.01 mol is 6.022 × 10^21
