A hexane solution contains as impurities 5.2% (by mass) hepatne and 2.9% (by mass) pentane. Calculate the mass of each component present in 93g of the solution.

93 x 0.029 = ??g

93 x 0.052 = ??g

It was that easy. I think I was trying to make it harder than it was. Thanks for the help

To calculate the mass of each component present in the solution, we'll first need to find out the mass of hexane, heptane, and pentane in the 93g solution.

1. Calculate the mass of hexane:
Since the mass percent of hexane in the solution is not given, we can assume that the remaining percentage is for hexane. This can be calculated as follows:
Mass of hexane = (100% - mass percent of heptane - mass percent of pentane) * Total mass of the solution
Mass of hexane = (100% - 5.2% - 2.9%) * 93g

2. Calculate the mass of heptane:
The mass percent of heptane is given as 5.2%, so we can calculate its mass as follows:
Mass of heptane = Mass percent of heptane * Total mass of the solution
Mass of heptane = 5.2% * 93g

3. Calculate the mass of pentane:
The mass percent of pentane is given as 2.9%, so we can calculate its mass as follows:
Mass of pentane = Mass percent of pentane * Total mass of the solution
Mass of pentane = 2.9% * 93g

Now, let's carry out the calculations:

1. Mass of hexane = (100% - 5.2% - 2.9%) * 93g
Mass of hexane = 91.9% * 93g = 91.9/100 * 93g = 85.347g

2. Mass of heptane = 5.2% * 93g
Mass of heptane = 5.2/100 * 93g = 4.836g

3. Mass of pentane = 2.9% * 93g
Mass of pentane = 2.9/100 * 93g = 2.697g

Therefore, in a 93g solution, there is approximately 85.347g of hexane, 4.836g of heptane, and 2.697g of pentane.
