Urea `[(NH_2)_2CO]` is prepared by reacting ammonia with carbon dioxide. `2NH_3(g) + CO_2(g) (NH_2)_2CO (aq) +H_2O(l)` In one process, 637.2 g of NH3 are treated with 1142 g of `CO_2` .
Calculate the mass of `(NH_2)_2CO` formed.

Text Solution

Verified by Experts

The molar mass of `(NH_2)_2CO ` is 60.06 g. We use this as a conversion factor to convert from moles of `(NH_2)_2CO` to grams of `(NH_2)_2CO` .
mass of `(NH_2)_2CO = 18.71 "mol" (NH_2)_2CO xx (60.6 g (NH_2)_2CO)/(1"mol")`
` = 1124 g (NH_2)_2CO`
