    Explanation:

    Equation for the reaction is given as;

    P4 + 5O2 - -> P4O10

    From the equation, 1 mole of P4 produces 1 mole of P4O10.

    Mass = Number of moles * molar mass

    Mass of P4 = 1 mol * 123.88 g/mol = 123.88 grams

    Mass of P410 = 1 mol * 283.886 g/mol = 283.886 g

    This means 123.88 grams of P4 produced 283.886 g of P4O10.

    How many kilograms of P4O10 would be produced from 410. g of pure P4?

    123.88 = 283.886

    410 = x

    x = (410 * 283.886) / 123.88

    x = 939.56g

    Upon converting to Kilogram by dividing by 1000

    x = 0.93956kg
