A football field is 0.001 km in length. Since the 1 is in the thousands place, you’d have to run back and forth (0.001 km) 1000 times.


0.001 x 1000 = 1

Which of the following statements describes the correct method of preparation of 1.00 L of a 2.0 M urea solution?
Zolol [24]

Answer:

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 = (2\times 60.06)g=120 g

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.
