How man Liters are there in 450 grams of NH3 gas at STP?

There are 593 liters of NH3 gas at STP.

Explanation:

We use the ideal gas formula, with the constant R = 0.082 l atm / K mol. First, we calculate the number of moles of NH3 (we obtain the mass of 1 mol from the atomic weights of the elements of the periodic table). The STP conditions are : 1 atm pressure and 273 K temperature. Solve for the formula, V (volume):

Weight 1 mol NH3 = Weight N + (Weight H) x3 = 14 g + 3 x 1 g=17 g/mol

17 g - --1 mol NH3

450 g--x = (450 g x 1 mol NH3) / 17g = 26,47 mol NH3

PV=nRT - --> V = (nRT) / P

V = (26,47 mol x 0.082 l atm / K mol x 273 K) / 1 atm

V=592, 57 L
