Question

120g urea is dissolved in 500g water calculate molarity​

Answer 1

Answer:

givena mass of urea = 120 g

amount of water= 500g .

moles = 120/ 60= 2 moles.

volume of solution = mass of solution / density of

solution.

120+ 500= 620 .

620/1.15= 539.13 ml

or 0.539 liters.

molarity is = no of moles/ volume of

solution.

= 2/ 0.539

= 3.71
