There are 3 carbon + 8 hydrogen + 1 oxygen = 12 atoms..!!
The chemical formula for maltose is C12H22O11, so there are a total of 12 carbon atoms in a molecule of maltose. A molecule of maltose has 11 oxygen atoms, not 12.
The number of atoms in a molecule depends on its formula. The definition of a mole is approximately 6.022 x 10^23 entities (like atoms or molecules). For example, a molecule of water (H2O) contains 3 atoms - 2 hydrogen and 1 oxygen.
Silicon tetrachloride (SiCl4) contains one silicon atom and four chlorine atoms, making a total of five atoms in the molecule.
PO4-3 is not a molecule it is an ion which contains one phosphorus and four oxygen atoms.
The subscripts in a chemical formula representing a single molecule, are the numbers of atoms of each atom in one molecule (remember no subscript is understood to be 1. So add the subscripts to get the total number of atoms in one molecule of a substance. 8+10+4+2=24 atoms in a single molecule of C8H10N4O2.
200 molecules C3H8O (1 mole C3H8O/6.022 X 10^23)(3 mole C/1 mole C3H8O)(6.022 X 10^23/1 mole C) = 600 molecules of carbon atoms -------------------------------------------- Of course, you can just look at this set up and see there are 600 molecules. My answer set up is a formal set up. ( 200 * 3 would do it )
C3H8O ==== Count them.
C3H8O ==== Count them.
A molecule of serotonin has 26 atoms in total.
The molecule of sodium thiosulfate, Na2S2O3, contains 9 atoms in total.
there are a total of 10 atoms in ribose
4 atoms in total. Oxygen is a diatomic molecule, so there is 2 atoms per molecule.
There are a total of 35 hydrogen atoms in 5 molecules of isopropyl alcohol C3H7O. Each molecule contains 8 hydrogen atoms (7 in the three carbon-hydrogen bonds and 1 in the hydroxyl group), so 5 molecules would have 5 x 8 = 40 hydrogen atoms in total.

The total no. of atoms present in C12H22O11 is 45.
An ethanol molecule consists of 2 carbon atoms, 6 hydrogen atoms, and 1 oxygen atom. Therefore, there are a total of 9 atoms in an ethanol molecule.
The chemical formula for maltose is C12H22O11, so there are a total of 12 carbon atoms in a molecule of maltose. A molecule of maltose has 11 oxygen atoms, not 12.
