1.	1.7 g of an unknown gas occupies 2.24 L at N.T.P Calculate its molecular mass. Identify the gas.
Answer» SOLUTION :2.24 L of the GAS of N.T.P has mass = 1.7 G 22.4 L of the gas at N.T.P has mass `= ((1.7g))/((2.24L))xx(22.4L)=17g` The molecular mass of gas `= 17 "g mol"^(-1)` The gas is AMMONIA `(NH_(3))`
