3 molecules of methanol (CH3OH) contain a total of 21 atoms. Each methanol molecule consists of 5 atoms: 1 carbon atom, 4 hydrogen atoms, and 1 oxygen atom. Therefore, 3 molecules would have 21 atoms (5 atoms x 3 molecules + 1 atom for the extra carbon in the last molecule).
Methanol has a single carbon it its center with , 3 hydrogens and 1 hydroxyl (OH) group attached for a total of: 1 carbon atom 4 hydrogen atoms 1 oxygen atom
NaHCO3 has 3 atoms (the subscript number of O) in 1 molecule, so .... in two molecules ....., you see
There are 12 chlorine atoms in four phosphorus trichloride (PCl3) molecules because each PCl3 molecule contains 3 chlorine atoms. Multiplying 3 chlorine atoms in each molecule by 4 molecules gives a total of 12 chlorine atoms.
1 formula unit of aluminum sulfate has the formula Al2(SO4)3. So there are 2 atoms of aluminum, 3 atoms of sulfur and 12 atoms of oxygen in 1 formula unit of aluminum sulfate. There are no molecules of aluminum sulfate. They are called formula units.
Three molecules of calcium carbonate (CaCO3) has nine(9) oxygens. Think of 3CaCO3 = CaCO3 + CaCO3 + CaCO3. Each molecule of CaCO3 has ;- 1 atoms of calcium (Ca) 1 atom of carbon (C) 3 atoms of oxygen (O3 = O + O + O). So if one molecules of CaCO3 has 3 oxygens, then three molecules of CaCO3 has 3 x 3 = 9 oxygens. The answer!!!!!
Methanol has a single carbon it its center with , 3 hydrogens and 1 hydroxyl (OH) group attached for a total of: 1 carbon atom 4 hydrogen atoms 1 oxygen atom
If we have 3 molecules of MgO and 3 molecules of H2O, this is equivalent to a total of 3 atoms of magnesium (Mg), 3 atoms of oxygen (O), and 6 atoms of hydrogen (H).
There are 2 atoms and 3 molecules in oxygen.
Chemical name for CaSO4 is calcium sulphate. It has 4 oxygen atoms in 1 molecule. So it has 12 oxygen atoms in 3 molecules.
It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
3 oxygen atoms in three molecules of water.- There are 3 total atoms in water, which is H2O. There are 2 hydrogen atoms (H), and 1 oxygen atom (O).
3 oxygen atoms in three molecules of water.- There are 3 total atoms in water, which is H2O. There are 2 hydrogen atoms (H), and 1 oxygen atom (O).
It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
Six 3x2=6 atoms, in 3 molecules of H2
NaHCO3 has 3 atoms (the subscript number of O) in 1 molecule, so .... in two molecules ....., you see
6 atoms of oxygen are present. Three O2 contains 6 O atoms.
There are 12 chlorine atoms in four phosphorus trichloride (PCl3) molecules because each PCl3 molecule contains 3 chlorine atoms. Multiplying 3 chlorine atoms in each molecule by 4 molecules gives a total of 12 chlorine atoms.
