Question

how many molecules and moles are there in 50 gram of 1 molecules of H2O​

Answer 1

Explanation:

Water has a molar mass of 18.015 g/mol . This means that one mole of water molecules has a mass of 18.015 g . So, to sum this up, 6.022⋅1023 molecules of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g .
