Answer: if you have a mixture of liquids, generally of varying boiling points, Distillation is a very useful technique. One of the simplest setups involves a Round bottom Flask w/ a thermometer in the top, with its bulb at where it is near a tube angled slightly downward out into a condenser.

As the flask is heated, the more volatile (lower B.P.) liquids will rise as fumes, register a temperature, and in the condenser, become liquid again. As this process continues, and you take the fractions at differing temps,

You can efficiently separate the various components If the Boiling Points are not too similar. There is more, but this is a good start.

Urea, (NH2)2CO, is a product of metabolism of proteins. An aqueous solution is 37.2% urea by mass and has a density of 1.032 g/m
Feliz [49]

Answer:

The molarity of urea in this solution is 6.39 M.

Explanation:

Molarity (M) is <em>the number of moles of solute in 1 L of solution</em>;  that is

molarity = moles of solute ÷ liters of solution

To calculate the molality, we need to know the number of moles of urea and the volume of solution in liters. We assume 100 grams of solution.

Our first step is to calculate the moles of urea in 100 grams of the solution,

using the molar mass a conversion factor. The total moles of 100g of a 37.2 percent by mass solution is

60.06 g/mol ÷ 37.2 g = 0.619 mol

Now we need to calculate the volume of 100 grams of solution, and we use density as a conversion factor.

1.032 g/mL ÷ 100 g = 96.9 mL

This solution contains 0.619 moles of urea in 96.9 mL of solution. To express it in molarity, we need to calculate the moles present in 1000 mL (1 L) of the solution.

0.619 mol/96.9 mL × 1000 mL= 6.39 M

Therefore, the molarity of the solution is 6.39 M.

What begins to happen to radioactive uranium as soon as a mineral containing it crystallizes from magma?
Aleonysh [2.5K]
<span>The radioactive uranium decays into its daughter product, lead. It would do this in magma as well, as nuclear decay depends on forces within the atom, not on the phase of the material in which the atom is a part.</span>
