To solve this, let's assume ideal gas behavior.
PV=nRT
Let's solve for n. Convert units to SI units first.
Pressure = 833 torr(101325 Pa/760 torr) = 111,057.53 Pa
Volume = 250 mL(1 L/1000 mL)(1 m³/1000 L) = 2.5×10⁻⁴ m³
Temperature = 42.4 + 273 = 315.4 K
n = (8,314 J/mol·K)(315.4 K)/(111057.53 Pa)(2.5×10⁻⁴ m³)
n = 94.45 mol
The molar mass of ammonia is 17.031 g/mol.
Mass = 94.45*17.031 = <em>1,608.51 g ammonia</em>
The tubes 1, 5 and 6 is the answer to the question which test tubes were used to determine the optimal ph lipase activity. Lipase is an enzyme and optimum ph the maximum possible point on which enzyme become active.

Answer:
C
Explanation:
The non metal in HCl is Chlorine and the name of the acid is Hydrochloric acid.
H = hydro
Cl = chloric
So I imagine this new acid, yet to be discovered even by the crew of the Star Ship enterprise, would be
HydroBlobbic acid
I await news from Spock on how things are going on the discovery of such a thing. So far he has not said anything about it.
Answer:
then it would still be 101.3
Explanation: because if it's constant that means it remained still
