The mass of 112 ~cm ³ of NH ₃ gas at STP is

Options

  1. A0.085 ~g
  2. B0.850 ~g
  3. C8.500 ~g
  4. D80.500 ~g

Correct answer

A. 0.085 ~g

Step-by-step solution

1 ~mol of NH ₃=17 ~g =22400 ~cm ³ at STP i.e., 22400 ~cm ³ of NH ₃ at STP have mass =17 ~g 112 ~cm ³ of NH ₃ at STP will have mass = 17 22400 112=0.085 ~g
