Question

Chalk contains 3% of carbon , 10% of calcium and 12% of oxygen . Find the amount in grams of each of these substance in 1 kg of chalk

Answer 1

Given, Chalk is 1 kg = 1000 g


Amount of chalk in carbon = 3/100 * 1000

                                             = 30g

Amount of Calcium in chalk = 10/100 * 1000
             
                                                = 100g

Amount of Oxygen in chalk = 12/100 * 1000

                                                = 120 g


Hope this helps!
