Answer 2

Answer:

1200g or 1kg 200g

Step-by-step explanation:

The total contents in gunpowder add up to 100%.

If you add nitre and sulphur and subtract it from the total, you will get the percentage of charcoal.

Charcoal = 100% - 85% = 15%

Now to convert the percentage to amount in unit-

$Amount = \frac{Percentage of charcoal}{100} x Amount of gunpowder$

= 15/100 x 8000  (Converted 8 kg to grams)

= 1200g or 1kg 200g

Therefore, the charcoal contents in the gunpowder is 1200g or 1kg 200g.

Hope this helps...
