Question 40

Hydrogen is added to an unsaturated oil. The total mass of product formed is measured.

After 4 min, the total mass of product is 6.0 kg.

From 4 min to 10 min, the mean rate of formation of the product is 2.0 kg min−12.0\,\mathrm{kg\,min^{-1}}2.0kgmin−1.

What is the total mass of product formed after 10 min?
