R . M . M = 2 × V . D . Vapour density is the density of vapour in relation to that of hydrogen. It may be defined as the mass of a certain volume of a substance divided by the mass of the same volume of hydrogen.

Nitroglycerine is used as an explosive. The equation for the explosive reaction is: 4 C 3 H 5 ( NO 3 ) 3 → 12 CO 2 + 10 H 2 O + 6 N 2 + O 2 ( l ) ( g ) ( l ) ( g ) ( g ) (Atomic mass of C = 12, H = 1, N = 14, O = 16) How many moles does the equation show for nitroglycerine?

4 C 3 H 5 ( NO 3 ) 3 → 12 CO 2 + 10 H 2 O + 6 N 2 + O 2 The number of moles is shown by nitroglycerine = 4 moles . The mole is the base unit of the amount of substance in the International Unit of System of Units (SI). It is defined as exactly 6 . 022 × 10 23 elementary particles, which may be atoms, molecules, ions, or electrons.

The number of moles of nitroglycerine is 4. The number of moles of gas produced by 4 moles of nitroglycerin are- The number of gas molecules = 12 CO 2 + 6 N 2 + O 2 = 12 + 6 + 1 = 19 moles The mole is the base unit of the amount of substance in the International Unit of System of Units (SI). It is defined as exactly 6 . 022 × 10 23 elementary particles, which may be atoms, molecules, ions, or electrons.

Nitroglycerine is used as an explosive. The equation for the explosive reaction is: 4 C 3 H 5 ( NO 3 ) 3 → 12 CO 2 + 10 H 2 O + 6 N 2 + O 2 (Atomic mass of C = 12, H = 1, N = 14, O = 16) How many moles of gas molecules are obtained from 1 mole of nitroglycerine.

4 moles of nitroglycerine give 19 moles of gas molecules. 1 mole of nitroglycerine gives = 19 4 = 4 . 75 moles Hence, 1 mole of nitroglycerine produces 4.75 moles of gas. The mole is the base unit of the amount of substance in the International Unit of System of Units (SI). It is defined as exactly 6 . 022 × 10 23 elementary particles, which may be atoms, molecules, ions, or electrons.

Mass of 1 mole of nitroglycerine [ C 3 H 5 ( N O 3 ) 3 ] = C ( 3 × 12 ) + H ( 1 × 5 ) + N ( 3 × 14 ) + O ( 9 × 16 ) = C ( 36 ) + H ( 5 ) + N ( 42 ) + O ( 144 ) = 227 g Mass of 1 mole of nitroglycerine is 227g. The total sum of the masses of the atoms of elements present in a molecule is termed as molecular mass.
