Maximum no. of hydrogen atoms are in-
1)16 gof CH4
2)31.2 g of C6H4
3)34.2g of C12H22O11
4)36 g of C6H12O6
SIR/MADAM,CAN U PLEASE GIVE THE EXPLANATION FOR THIS SUM AND ALSO NOTE ,ON WHICH CONCEPT IS IT BASED ON, IT'S FORMULA...
The number of atoms of an element in a molecule depends on the moles of the substance present in the given mass and number of atom of the element present per molecule.
To solve, use the formula: mole = mass/molar mass to determine the moles of the different molecules
Number of atoms of the hydrogen is given in the molecular formula
We repeat the same for the rest of the molecules.
To solve, use the formula: mole = mass/molar mass to determine the moles of the different molecules
Number of atoms of the hydrogen is given in the molecular formula
- 16g of CH4 Molar mass = 16g/mol
Moles of CH4 = 16/16 = 1mol
Number of molecules of CH4 = moles Avogadro number (NA) = 1 NA
Each molecule of CH4 contains 4 hydrogen atoms (subscript below H is the number of atoms)
So, number of hydrogen atoms in CH4 are = 4 1 NA = 4NA
(Avogadro number does not affect the result, so it is not included as a number in the calculation).Number of molecules of CH4 = moles Avogadro number (NA) = 1 NA
Each molecule of CH4 contains 4 hydrogen atoms (subscript below H is the number of atoms)
So, number of hydrogen atoms in CH4 are = 4 1 NA = 4NA
We repeat the same for the rest of the molecules.
- 31.2g of C6H4 molar mass = 76g/mol
Moles = 31.2/76 = 0.41mol
Number of H atoms = 4 0.41 NA = 1.6 NA
Number of H atoms = 4 0.41 NA = 1.6 NA
- 34.2g of C12H22O11 molar mass= 342g/mol
Moles = 34.2/342 = 0.1mol
Number of H atoms = 22 0.1 NA= 2.2 NA
4. 36g of C6H12O6 molar mass= 180g/mol
Number of H atoms = 22 0.1 NA= 2.2 NA
Moles = 36/180 = 0.2mol
Number of H atoms = 12 X 0.2 X NA = 2.4 NA
Maximum number of Hydrogen atoms are in 16g of CH4Number of H atoms = 12 X 0.2 X NA = 2.4 NA
