Question

Convert from grams to moles for 22gH2O

Answer 1

Answer:mole =22gm/ 18gm = 1.22moles

Explanation:A mole is calculated by dividing the given weight from molecular weight of the compound. In this case Molecular weight of H2O = 18 grams. So answer is 22/18= 1.22

Answer 2

Moles = 1.22 moles

Step-by-step explanation

Given

Mass of water = 22 g

We know the molar mass of water = 18,01528 g/mol

Required: Moles of H2O

Solution

To calculate the number of moles, use

n = m/M where n is the moles, m is the mass and M is the molar mass

n = 22g/18,01528 g/mol

n = 1.22 mol
