Question

B. If you had 65.0 grams of charcoal, how many grams of black powder could you make?

Answer 1

`m_(powder)=433g`

Step-by-step explanation:

Hello there!

In this case, according to the composition of the black powder - 75% potassium nitrate, 15% charcoal and 10% sulfur, we can see that starting by 65.0 grams of charcoal, the produced amount of the black powder would be:

`15.0\%=(m_(charcoal))/(m_(powder)) *100\%\\\\m_(powder)=(m_(charcoal))/(15.0\%) *100\%\\\\m_(powder)=(65.0g)/(15.0\%) *100\%\\\\m_(powder)=433g`

Best regards!
