gunpowder is a mixture of potassium nitrate , sulfur and carbon in th proportion (by mass) of 6:1:1 (KNO3;S:C). A typical riflr shell contains 3.2 gunpowder. How many moles of each compnent are there in our sample gunpowder?

KNO3 mole:
C: mol
S: mol

Thank you for helping!!

    You omitted the units of 3.2? Is that 3.2 grams? If so, read on. If not, the following is not correct.
    So you have 6 + 1 + 1 total = 8 parts of which 6/8 is KNO3, 1/8 is C and 1/8 is S.
    3.2 x (6/8) = 2.4 grams KNO3.
    3.2 x (1/8) = 0.4 grams S.
    3.2 x (1/8) = 0.4 grams C.

    Now convert to moles. moles = grams/molar mass.
