Here are some solve problems based on conversion of moles to grams of a substance.

Solved Examples

Question 1: How many grams of NaOH is present in 0.650 moles of NaOH.
Solution:
 
Given : Mass of NaOH = 0.650 moles

Formula weight of NaOH = 22.98977 + 15.9994 + 1.00794 = 39.99711 g/mol

Mass of NaOH in grams = Moles of substance $\times$ Formula weight

Mass of NaOH in grams = 0.650 $\times$ 39.99711

Mass of NaOH in grams = 25.9981 grams.
 

Question 2: How many grams of H$_{2}$O is present in 2.3 moles of H$_{2}$O.
Solution:
 
Given : Mass of H$_{2}$O = 2.3 moles

Formula weight of H$_{2}$O = 1.00794 $\times$ 2 + 15.9994 = 18.01528 g/mol

Mass of H$_{2}$O in grams = Moles of substance $\times$ Formula weight

Mass of H$_{2}$O in grams = 2.3 $\times$ 18.01528

Mass of H$_{2}$O in grams =  41.4351 grams.
