    Complete question:

    This is the chemical formula for nickel tetracarbonyl (a powerfully poisonous liquid used in nickel refining) : Ni (CO) 4 A chemical engineer has determined by measurements that there are 9.6 moles of nickel in a sample of nickel tetracarbonyl. How many moles of carbon are in the sample? Round your answer to 2 significant digits.

    Answer:

    number of moles of carbon in the compound = 9.6 * 4 = 38.40 moles ≈ 38 moles

    Explanation:

    The molecular formula of the compound, tetracarbonyl is represented as Ni (CO) 4. From the chemical formula of the actual compound contains 1 mole of nickel, 4 moles of carbon and 4 moles of oxygen.

    The ratio of the moles can be represented as:

    Ni C O

    1 : 4 : 4

    1 mole of Nickel containing mass of 58.6934 g.

    4 moles of carbon containing mass of 4 (12 g) = 48 g

    4 moles of oxygen containing mass of 4 (16 g) = 64 g

    since 1 mole of nickel contains 4 moles of carbon in the compound

    9.6 moles of nickel will contain? moles of carbon

    cross multiply

    number of moles of carbon in the compound = 9.6 * 4 = 38.40 moles

    2 significant figure = 38 moles

    9.6 moles

    Explanation:

    The compound; Ni (CO4)

    The ratio of the elements is given as;

    Ni : C : O

    1 : 1 : 4

    The ratio of Nickel is particularly;

    Ni : C

    1 : 1

    If there are 9.6 moles of Nickel present in the sample, it means there are also 9.6 moles of Carbon in the sample.
