The density of the gas can be given by the mass of the substance and its volume. A 4084 gms of ammonia has a volume of 5.99 L.
<h3>What is STP?</h3>
STP is the condition at which the temperature and the pressure of the gas are at the normal and standard conditions.
The density of the ammonia = 681.9gm/L
The mass = 4084 gm
The volume is calculated as:
V = Mass ÷ Volume
= 4084 ÷ 681.9
= 5.99 L
Therefore, at STP the volume of ammonia is 5.99 L.

Answer: Molarity is defined as moles of solute per liter of solution. So, find the moles of solute and divide by the liters of solution.
molar mass AlCl3 = 133g/mole
moles AlCl3 = 127 g x 1 mole/133 g = 0.955 moles
liters of solution = 400 ml x 1 liter/1000 ml = 0.400 liters
Molarity = 0.955 moles/0.400 liters = 2.39 M
