To convert grams to moles, you need to use the molar mass of the substance.
First, determine the molar mass of the substance. For example, if you are converting 105g of water (H2O), the molar mass is:
2(1.01g/mol) + 16.00g/mol = 18.02g/mol
Next, divide the given mass by the molar mass to find the number of moles:
105g / 18.02g/mol ≈ 5.82 moles
Therefore, 105g of water is approximately equal to 5.82 moles.
