Question

chalk contains calcium,carbon dioxide and oxygen in the ratio 4:5:6 find the percentage of each component in chalk​

Answer 1

Answer:

Calcium = 26.7%

CO² = 33.3%

Oxygen = 40%

Ratio :-

Calcium = 4x

Carbon dioxide = 5x

Oxygen = 6x

Total ratio = 15x

Percentage :-

Calcium = (4x * 100)/15x. = 26.7 %

Carbon dioxide = (5x * 100)/15x. = 33.3%

Oxygen = (6x * 100)/15x. = 40%

Total = 26.7% + 33.3% + 40%

26.7% + 33.3% + 40% = 100%
