Which of the following statements describes the correct method of preparation of 1.00 l of a 2.0 m urea solution?
urea = 60.06 g/mol
a) dissolve 120 g of urea in 1.00 kg of distilled water.
b) dissolve 120 g of urea in 880 g of distilled water.
c) dissolve 120 g of urea in enough distilled water to produce 1.00 l of solution.
d) dissolve 120 g of urea in 1.00 liter of distilled water.
e) the density of urea is needed in order to do this calculation

To prepare 1.00 L of 2.0 M urea solution, we need to dissolve 120 g of urea in enough water to produce a total of 1.00 L solution

Explanation:

Molarity of a solute in a solution denotes number of moles of solute dissolved in 1 L of solution.

So, moles of urea in 1.00 L of a 2.0 M urea solution = 2 moles

We know, number of moles of a compound is the ratio of mass to molar mass of that compound.

So, mass of  2 moles of urea =

Therefore to prepare 1.00 L of 2.0 M urea solution, we need to dissolve 120 g of urea in enough water to produce a total of 1.00 L solution

So, option (C) is correct.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
