Question

chalk contains calcium (40%),carbon (12%) and oxygen (48%). Find the amount (in grams) of each in 2.5kg of chalk.​

Answer 1

Answer:

total amount of chalk=2.5 kg= 2500 grams

amount of calcium in chalk=40/100 * 2500 g

                                           1000 g

amount of carbon in chalk= 12/100 * 2500 g

                                           =300 g

amount of oxygen in chalk= 48/100 * 2500 g

                                            =1200 g
