Answer:
pressure and temperature are directly proportional.
Explanation:
At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. Also given a constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas.
This means that if V is constant then
P = n (RT/V) then n= PV/RT. As P is increased, T is also increased thereby decreasing the value of n since pressure and temperature are directly proportional.
Significant figures means the number of important figures, 0 not included.
This means that the answer is 1094.00

I think that’s it
Answer:
Mass = 3.752 g
Explanation:
Given data:
Number of moles of Li = 0.536 mol
Mass of N₂ needed = ?
Solution:
Chemical equation:
2Li + N₂ → 2LiN
Now we we will compare the moles of Li and N₂.
Li : N₂
2 : 1
0.536 : 1/2×0.536 = 0.268 mol
Mass of N₂
Mass = number of moles × molar mass
Mass = 0.268 mol × 14 g/mol
Mass = 3.752 g
