Scientists estimate that 2 x 1016g of calcium hydroxide would be required per year to counteract the effects of modern CO2emissions .

I need help with this word problem I'm lost - thank you....Scientists estimate that 2 x 1016g of calcium hydroxide would be required per year to

counteract the effects of modern CO2emissions . This amount is

impractical, but it suggests something about the rate at which CO2 is absorbed into the

oceans. How many grams of CO2are absorbed by the world's oceans per year?

CO2 (g) + Ca(OH)2 (aq)  CaCO3 (s) + H2O (l)
