MCQ
Which of the following has maximum mass
- A$0.1\ g$ atom of $C$
- B$0.1\ mole$ of $NH_3$
- C$6.02 × 10^{22}$ molecule of $H_2$ gas
- ✓$1120\ ml$ of $CO_2$ at $1\ atm, 273\ K$
$22400 = 44$
$1120 = \frac {1120}{22400} \times 44 = 2.2\ g$

${K_p} = 8 \times {10^{ - 2}}$$C{O_{2(g)}} + {C_{(s)}} \to 2C{O_{(g)}}$ ; ${K_p} = 2$
$CaC{{O}_{3(s)}}\xrightarrow{\Delta }Ca{{O}_{(s)}}+C{{O}_{2}}\uparrow $; ${{K}_{p}}=8\times {{10}^{-2}}$
$(a)\, \Delta U = 0$
$(b)\, q = 0$
$(c)\, \Delta T = 0$
$(d)\,q = 2.303\,nRT\,{\log _{10}}\,\left( {\frac{{{V_2}}}{{{V_1}}}} \right)$
