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

the answer is the
