A chemist mixes 85.5 g of carbon tetrachloride with 3.84 g of isopropenylbenzene and 26.7 g of thiophene.
Calculate the percent by mass of each component of this solution.
Be sure each of your answer entries has the correct number of significant digits.
isopropeny benzene
To calculate the percent by mass of each component in the solution, you need to first calculate the total mass of the solution, and then determine the mass percent of each component.
Total mass of solution = 85.5 g + 3.84 g + 26.7 g = 116.04 g
Percent by mass of carbon tetrachloride:
(85.5 g / 116.04 g) x 100% = 73.71 %
Percent by mass of isopropenylbenzene:
(3.84 g / 116.04 g) x 100% = 3.31 %
Percent by mass of thiophene:
(26.7 g / 116.04 g) x 100% = 23.0 %
Therefore, the percent by mass of each component in the solution is:
- Carbon tetrachloride: 73.71 %
- Isopropenylbenzene: 3.31 %
- Thiophene: 23.0 %
