Answer:


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!
