Hi there!
The molar mass of water is 18 grams. The mass of water, present in the given sample, is 100 grams.
The number of moles in the sample can be calculated by dividing the mass given by molar mass.
Moles = mass / molar mass
Moles = 100 grams / 18 grams
Moles = 5.56
The number of particles in a mole of a substance is 6.022 x 10²³. The total number of molecules in 5.56 moles of water is;
Number of molecules = 5.56 x 6.022 x 10²³
Number of molecules = 33.456 x 10²³
Cheers!
