Answer 2

Answer:

Quantity of Charcoal is 1.35 kg

Step-by-step explanation:

Quantity of Nitrate in the Gunpowder by Percent = 75%

Quantity of Sulphur in the Gunpowder by Percent = 10%

Hence, quantity of Charcoal in Gunpowder by Percent = {100 - (75+10)}%

                                                                                    = 15%

Total Amount of Gunpowder = 9kg

Hence, Quantity of Charcoal = (15% of 9kg)

                                            = $\frac{15}{100}$ × 9 kg

                                            = 1.35kg or 1350g
