4 = Parts Molecule.

One molecule of H2O has 3 atoms (two hydrogens and one oxygen). So there will be 12 atoms in 4H2O.
if you mean carbon dioxied, the formula is: CO2 If you mean carbon monoxied, the formula is: CO If you mean Carbon Dioxide, the formula is: CO2 If you mean Carbon Monoxide, the formula is: CO [Corrections for spelling only]
Based on the formula of M3(PO4)4, that would mean the M has an oxidation number of 4+, so the metal chloride would take the form of MCl4
Methane has the formula CH4. So its molecular weight is 12 + 4 = 16. Is that what you mean?
Cadmium sulfite is CdSO3
Do you mean the molecular formula? If so, then it is C4H10. If you mean empirical formula, then it is C2H5.
4
2Ag20 --> 4Ag + 02 Fe304 + 4H2 --> 4H20 + CuCl2
One molecule of H2O has 3 atoms (two hydrogens and one oxygen). So there will be 12 atoms in 4H2O.
CHCl3 is the chemical formula of trichloromethane (chloroform); the meaning of 4 is four molecules.
Formula for finding the surface area of a sphere = 4*pi*radius2 in square units. Formula for finding the volume of a sphere = 4/3*pi*radius3 in cubic units. Or did you mean the formula for finding the area of a square? in which case it is Length*Height in square units.
A formula does not normally have a mean!
Add together all 4 sides if you mean a parallelogram
If you mean 4*pi*r^2 then it is the formula for finding the surface area of a sphere
The geometric mean of two numbers is the square root of their product. For example, the geometric mean of 4 and 25 is 10.
You need to explain what you mean by '4 mb'.
