Dry air was drawn through bulbs containing a solution of 40 grams of urea in 300 gram of water, then through bulbs containing pure water at the same temperature and finally through a tube in which  pumice moistened with strong.`H_(2)SO_(4)` was kept. The water bulbs lost 0.0870 grams and the sulphide acid tube gained 2.036 grams. Calculate the molecular weight of urea.
