Hydrogen — 4.07% Carbon–24.27% Chlorine—71.65% Molar Mass Is 98.96G To Calculate Empirical Formulae, first, we have to divide the given percentages of atoms by their molecular masses. Hydrogen — 4.07 / 1 = 4.07 Carbon–24.27 / 12 = 2.02 Chlorine—71.65 / 35.5 = 2.01 Now we have to divide all the values with the lowest obtained value. Hydrogen — 4.07 / 2.01 = 2 Carbon–2.02 / 2.01 = 1 Chlorine— 2.01 / 2.01 = 1 Therefore, the empirical formula is CH2Cl To Calculate Molecular Formulae, we need to find the weight of the empirical formula CH2Cl 12 + 2*1 + 35.5 = 49.5 The molecular weight- 98.96 is double of empirical weight. Therefore molecular formula is C2H4Cl2

The dimensional formula of energy or heat = u = [ ML2T-2 ].
Assume that, M1, L1, T1 and M2, L2, T2 are the units of mass, length and time in given two systems.
{tex}\therefore{/tex} M1 = 1 kg, M2 = {tex}\alpha{/tex} kg
L1 = 1 m, L2 = {tex}\beta{/tex} m
T1 = 1 s, T2 = {tex}\gamma{/tex} s
n1 and n2 are the magnitudes of heat or energy of system one and system two respectively.
For a given physical quantity, the product of its magnitude and unit is always constant.
n1u1 = n2u2
or {tex}n _ { 2 } = n _ { 1 } \frac { u _ { 1 } } { u _ { 2 } } = 4.2 \times \frac { \left[ \mathrm { M } _ { 1 } \mathrm { L } _ { 1 } ^ { 2 } \mathrm { T } _ { 1 } ^ { - 2 } \right] } { \left[ \mathrm { M } _ { 2 } \mathrm { L } _ { 2 } ^ { 2 } \mathrm { T } _ { 2 } ^ { - 2 } \right] }{/tex}
{tex}= 4.2 \left[ \frac { \mathrm { M } _ { 1 } } { \mathrm { M } _ { 2 } } \right] \times \left[ \frac { \mathrm { L } _ { 1 } } { \mathrm { L } _ { 2 } } \right] ^ { 2 } \times \left[ \frac { \mathrm { T } _ { 1 } } { \mathrm { T } _ { 2 } } \right] ^ { - 2 }{/tex}
{tex}= 4.2 \left[ \frac { 1 } { \alpha } \right] \times \left[ \frac { 1 } { \beta } \right] ^ { 2 } \times \left[ \frac { 1 } { \gamma } \right] ^ { - 2 }{/tex}
n2 = 4.2{tex}\alpha ^ { - 1 } \beta ^ { - 2 } \gamma ^ { 2 }{/tex} new unit
Therefore, 1 cal = {tex}4.2 \alpha ^ { - 1 } \beta ^ { - 2 } \gamma ^ { 2 }{/tex} new unit

The narrator's grandfather's portrait hung above the mantelpiece in the drawing room. He wore a big turban and loose-fitting clothes. His long white beard covered the best part of his chest and he looked at least a hundred years old. He didn't look the sort of a person who would have a wife or children. He looked as he could only have grandchildren.
