Question

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

Answer 1

Answer:

$m_{powder}=433g$

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:

$15.0\%=\frac{m_{charcoal}}{m_{powder}} *100\%\\\\m_{powder}=\frac{m_{charcoal}}{15.0\%} *100\%\\\\m_{powder}=\frac{65.0g}{15.0\%} *100\%\\\\m_{powder}=433g$

Best regards!
