In which of the following compounds is the mass ratio of chromium to oxygen closest to 1.62 to 1.00?

ohaa [14]

Answer:

The answer to your question is letter A

Explanation:

Data

Mass ratio 1.62 to 1.00

Atomic mass Cr = 52 g

Atomic mass O = 16

Process

1.- Calculate the proportion Chromium to Oxygen to each possible solutions

a) CrO₃ = $\frac{52}{16 x 3} = \frac{52}{48} = 1.08$

b) CrO₂ = $\frac{52}{16 x 2} = \frac{52}{32} = 1.63$

c) CrO = $\frac{52}{16} = 3.25$

d) Cr₂O = $\frac{52 x 2}{16} = \frac{104}{16} = 6.5$
