About 45 million tons (us) of sulfuric acid are manufactured every year in the world; the largest amount (by weight) of any chemical produced by man. as produced it has a density of 1.82 gm/cm? a) what is the production rate of sulfuric acid per person on the earth in kg/person? b) what is the annual global production rate of sulfuric acid in yd?

To convert tons to kg you need to multiply it by 1000. So you have 45,000,000,000 kg of sulfuric acid produced each year in the world, you also know that the world population was 7,530,000,000 in 2017. So if you divide the amount of sulfuric acid by the world population you obtain the production rate, that is 5.976 kg/person. For the b), you know that 91.44 cm are 1 yd, and that 100 g are 1 kg, so you convert 1.82g/cm to 0.16642 kg/yd, now you just multiply it by 45,000,000,000 kg/year, so the annual rate in yd is 7,488,900,000 yd/year.
