Method:
Chromium = Cr3+ + Carbonate = CO3 2-
Cr3+ + CO32- = Cr2(CO3)3
Note how and where the numbers and compounds are replaced.
Sorry I can not explain in full but this is basically how its done.

∙ 12y agoThe molecular formula of Chromium Carbonate is Cr2(CO3)3
The Atomic Mass of Chromium is 51.9961 amu (averaged over the isotopes)
The atomic mass of Carbon is 12.0107 amu (averaged over the isotopes)
The atomic mass of Oxygen is 15.9994 amu (averaged over the isotopes)
So the molecular mass of Chromium Carbonate is:
2x51.9961 + 3(12.0107 + 3x15.9994) = 284.0189 amu

because carbonate has a 2- charge and here chromium has a 2+ charge

What is the chemical name for Bi2CO33?
Chromium (II) Carbonate. Although I'm not sure Chromium (II) can form, there might be an overall charge on your formula there...
What is the formula name for Cr C2H3O2 3?
chromium (III) acetate at least this is what masteing chemistry told me after I guessed wrong three times I however am not to sure because my chem. teacher "doctor" Ott did not bother teaching me how to figure this out before she assigned it for homewor
Is chromium II carbonate a solid?
yes
What is the formula for chromium (III) fluoride?
the chemical formula for chromim(II) fluoride is CrF2
What is the name of the formula CrI2?
Chromium(II) Iodide
What is the compound name for CrCO3?
Chromium (II) Carbonate. Although I'm not sure Chromium (II) can form, there might be an overall charge on your formula there...
WHAT is the molecular formula for Ni 2CO3?
Nickel II carbonate
What is the chemical name for Bi2CO33?

Is chromium II carbonate a solid?
yes
What is the formula CrO?
CrO is the formula for chromium(II) oxide. Cr is the elemental symbol for chrome, and O represents oxygen. The molecular weight of CrO is 68.00 grams/per mole using two significant figures. Variants of CrO include II, III and VI.
What is the formula for chromium (III) fluoride?
the chemical formula for chromim(II) fluoride is CrF2
The name for the compound with the formula Cr2O3 would be written as what?
Cr2O3 is the chemical formula for chromium (III) oxide
Chromium IV oxide formula?
CrO2this is the incorrect formula. For Chromium II oxide the formula is actually CrO without the 2. The reason for this is simple. the II after chromium indicates that it has a charge of +2, and the oxygen, we know is in group 16, has a charge of -2. The formula CrO2 is actually the formula for chromium IV oxide>
What is the formula iron2 hydrogen carbonate?
The formula of iron II hydroxide is Fe (OH) 2
What is the name of the formula CrI2?
Chromium(II) Iodide
