Question

Silicon dioxide made up of elements silicon and oxygen contains 46.7% mass of silicon.With what mass of O2 will 10 grams of silicon combine?

Answer 1

Answer:

With what mass of oxygen will 10 g of silicon combine? Solution: 100g of silicon dioxide contains 46.7 g of silicon, or 100 – 46.7 ( i.e. 53.3 g) of oxygen. It means, 10g of silicon will contain (10/100) × 53.3 = 5.33 g of oxygen
