What is the empirical formula of an oxide of chromium that is 48% oxygen
AnnyKZ [126]

Answer:

CrO_3

Explanation:

Hello,

In this case, considering that the compound is 48% oxygen, we infer it is 52% chromium, therefore, by using their atomic masses we compute the moles by assuming those percentages as masses:

n_{Cr}=52g*\frac{1mol}{52g}=1mol\\ \\n_O=48g*\frac{1mol}{16g}=3mol

Next, by dividing by the smallest moles, we find the subscripts in the empirical formula:

Cr=\frac{1}{1} =1\\\\O=\frac{3}{1} =3

Which are also expressed in the smallest whole numbers, therefore the empirical formula is:

CrO_3

Which corresponds to the chromic oxide or chromium (IV) oxide.

Regards.
