How many molecules in 0.4 moles of h20?

Answer 1

Each mole of a substance contains 6.022 E23 molecules or atoms of that substance. Four moles of H2O will contain 2.4088 E24 molecules.

Answer 2

There are approximately 2.41 x 10^23 molecules of H2O in 0.4 moles. This calculation is based on Avogadro's number, which represents the number of particles in one mole of a substance.

Answer 3

0.4 mole x 6.022x1023 molecules/mole = 2.4088x1023 molecules

Answer 4

4.4 moles CO2 x 6.02x10^23 molecules/mole = 2.65x10^24 molecules of CO2

Answer 5

4 X 18 = 72 grams
