Steam at $100^{\circ} \mathrm{C}$ is passed into 114 g of water at $30^{\circ} \mathrm{C}$. The mass of water present in the mixture when the temperature of the water becomes $70^{\circ} \mathrm{C}$ is (Latent heat of steam $=540 \mathrm{cal} \mathrm{g}^{-1}$; specific heat capacity of water $=1 \mathrm{cal} \mathrm{g}^{-1}{ }^{\circ} \mathrm{C}^{-1}$ )

• Correct answer
  A

  $122 g$
• B

  $132 g$
• C

  $142 g$
• D

  $152 g$

Hence, the correct answer is option: 'A'.
