The total number of atoms present in the chemical formula of wolframite is ____ .
1 6
2 2
3 4
4 5
Explanation:
The chemical formula of wolframite (Ferrous tungstate) is \({\mathrm{\mathrm{FeWO}_{4}}}\). Hence, total number of atoms is 6 \({\mathrm{(1 \mathrm{Fe}, 1 \mathrm{~W}}}\) and 4 O\({\mathrm{)}}\)
