Dissolving 120g of urea (mol.wt.60) in 1000g of water gave a solution of density 1.15 g/mL. The molarity of the solution isA. 1.78 MB. 2.00 MC. 2.05 MD. 2.22 M

Dissolving 120g of urea (mol.wt.60) in 1000g of water gave a solution

1.	Dissolving 120g of urea (mol.wt.60) in 1000g of water gave a solution of density 1.15 g/mL. The molarity of the solution isA. 1.78 MB. 2.00 MC. 2.05 MD. 2.22 M
Answer» Correct Answer - C Mole `=(120)/(60)=2` mass of solution = 1120 g `V=(1120)/(1.15xx100)=(112)/(115)L` `M=(2xx115)/(112)=2.05` mol/litre
