The chemical formula of propane is C3H8; 11 atoms are present in the molecule.
20
Five molecules of propane have 40 hydrogen atoms.
The formula tells how many atoms of which elements are found in a molecule of propane. It indicates that there are 3 atoms of carbon and 8 atoms of hydrogen in a molecule of propane.
Since propane has the formula C3H8, each mole of propane will have 8 moles of hydrogen atoms, so 5 moles of propane will contain 5x8=40 moles of hydrogen.
Seven. The formula is H2SO4.

Propane has eleven atoms in it. It's CH3CH2CH3 or C3H8.
CH3-CH2-CH3 = PROPANE. there are there carbon atoms.
Five molecules of propane have 40 hydrogen atoms.

Since propane has the formula C3H8, each mole of propane will have 8 moles of hydrogen atoms, so 5 moles of propane will contain 5x8=40 moles of hydrogen.
4 oxygen atoms are present
0, there are no oxygen atoms in PROPANE (C3H8 or CH3CH2CH3)
By looking at an actual chemical formula for a compound, we could tell you how many hydrogen atoms there are per molecule (or at least per formula unit) of that compound.Without the specific chemical formula, we can't. So the question is meaningless ... how many hydrogen atoms are present in a chemical formula depends on what the chemical formula is.
There is 9.632x10^23 atoms of hydrogen in 0.200 moles of propane
there are 8 hydrogen atoms present in propane. There is 8 hydrogen atoms in propane, Each carbon has a valency of 4, 4 bonds with other atoms. Hydrogen has valency of 1. the general formula for alkanes is CnH2n +2 (n means number of that atom.) so to find how many hydrogens there with, say, 50 carbons you would do CnH2n + 2= C50H102. :)
Nine atoms represent the empirical formula of ammonium nitrate. Namely, 2 nitrogen atoms, 3 oxygen atoms and 4 hydrogen atoms.
Four, the chemical formula is K2SO4
