Question

7. The mass of a cylinder filled with gas is 25 kg 350 g and the mass of the empty cylinder is 12 kg 675 g What is the mass of gas contained in 25 such cylinders? ​

Answer 1

12 kg.

Explanation:

Difference in mass = Mass of gas filled cylinder - Mass of empty cylinder

= (25 kg 350 g) - (12 kg 675 g)

Convert:

12 kg 675 g = 12 kg + (675 g/1000) kg

= 12 kg + 0,675 kg

= 12,675 kg

Difference in mass

= 25 kg 350 g - 12.675 kg

= 12.675 kg

Difference in mass in kg

= 12 kg 675 g - 12.675 kg

= 12 kg
