Ammonia gas is passed into water, yielding a solution of density of 0.93

g/mL and containing 18.6% NH3 by weight. What is the mass of NH3 per mL of solution.

0.93 g/mL x 0.186 = grams NH3/mL

To find the mass of NH3 per mL of solution, we need to calculate the amount of NH3 in grams and divide it by the volume of the solution in mL.

First, let's assume we have 1 mL of the solution.

Given that the density of the solution is 0.93 g/mL, 1 mL of the solution would weigh 0.93 grams.

Next, we need to determine the amount of NH3 in grams present in the solution.

Given that the solution contains 18.6% NH3 by weight, we can calculate the mass of NH3 in grams by multiplying the weight percent by the total mass of the solution.

Mass of NH3 in grams = (18.6/100) * 0.93 grams

Now, we can divide the mass of NH3 by the volume of the solution to find the mass of NH3 per mL of solution.

Mass of NH3 per mL of solution = (18.6/100) * 0.93 grams / 1 mL

Thus, the mass of NH3 per mL of solution would be (18.6/100) * 0.93 grams.
