Explanation:
Molar mass
The mass present in one mole of a specific species .
The molar mass of a compound , can easily be calculated as the sum of the all the individual atom multiplied by the number of total atoms .
(a) S₈
Molar mass of of the atoms are -
sulfur, S = 32 g/mol.
Molar mass of S₈ = 8 * 32 g/mol. = 256 g/mol.
(b) C₂H₁₂
Molar mass of of the atoms are -
Hydrogen , H = 1 g/mol
Carbon , C = 12 g/mol
Molar mass of C₂H₁₂ = ( 2 * 12 ) + (12 * 1 ) = 36 g /mol
(c) Sc₂(SO₄)₃
Molar mass of of the atoms are -
sulfur, S = 32 g/mol.
oxygen , O = 16 g/mol.
scandium , Sc = 45 g/mol.
Molar mass of Sc₂(SO₄)₃ = (2 * 45 ) + ( 3 *32 ) + ( 12 * 16 ) = 378 g /mol
(d) CH₃COCH₃ (acetone)
Molar mass of of the atoms are -
Carbon , C = 12 g/mol
oxygen , O = 16 g/mol.
Hydrogen , H = 1 g/mol
Molar mass of CH₃COCH₃ (acetone) = (3 * 12 ) + ( 1 * 16 ) + ( 6 * 1 ) = 58g/mol
(e) C₆H₁₂O₆ (glucose)
Molar mass of of the atoms are -
Carbon , C = 12 g/mol
oxygen , O = 16 g/mol.
Hydrogen , H = 1 g/mol
Molar mass of C₆H₁₂O₆ (glucose) = ( 6 * 12 ) + ( 12 * 1 ) + ( 6 * 16 ) = 108g/mol.
Most common mineral acids solutions (HCl, H2SO4, HNO3, H3PO4, etc.) are prepared in water. Infact, system is<span> acidic only in aqueous medium.

However, in few cases, it isn't advisable/viable to perform reaction is aqueous medium. This can be due to poor solubility of reactant in water. This situation arises especially, if reactant is highly non-polar in nature.
There also exist a possibility that, reactant is not stable in aqueous medium. In such event, use of water has to be avoided.
For such reaction, solid camphorsulfonic acid is added in reaction, when acid is required to initiate/catalyst the reaction.
The major advantage that camphorsulfonic acid offers is that, it is solid and hence it is easy to weight. Also, they don't required water addition for the reaction.
Because of the pressure. No oxygen in the water, however there is oxygen above the sea level. Thus, causing pressure to our bodies.
