Question

White phosphorus (P4) is used to produce phosphorus oxides, such as P4O10. How many kilograms of P4O10 would be produced from 410. g of pure P4 ?

Answer 1

Answer:

0.93956kg

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
