Upon decomposition, one sample of magnesium fluoride produced 1.65kg of magnesium and 2.58kg of fluorine. A second sample produced 1.38kg of magnesium.

How much fluorine (in grams) did the second sample produce?

  1. (1.65/2.58) = (1.38/x)
    Solve for x.

  2. MgF2 produce

    Sample 1) 1.65 kg Mg
    2) 2.57 kg F

    Sample 1) 1.32 kg Mg
    2) ? g F

    1. Find the ratio from sample 1,
    1.65kg / 2,57kg = 0.64

    2. Using Law of define properties, the first and second should have the same ratio.

    1.3 kg / x kg F = 0.64
    x = 2.0625 kg F
    = 2062.5 g F
