Analysis of a silicon dioxide (SiO₂) sample indicated it contained 46.75 g of silicon and 53.25 g of oxygen. Determine the mass of silicon in a sample of SiO₂ if the mass of oxygen is 21.3 g. A) 116.9 g B) 24.26 C) 18.7 g D) 9.70 g E) 2.67 g

Question

Quizplus · Accepted Answer

The ratio of silicon to oxygen in the original sample is 46.75 g Si to 53.25 g O. Using this ratio, for 21.3 g of oxygen, the mass of silicon is (46.75/53.25) * 21.3 = 18.7 g.
