Answer:
The temperature of the gas after it is filled is 596 K
Explanation:
According to Gay-Lussac law, the pressure of a gas mass is directly proportional to temperature to a constant volume. That means than if pressure rise, the temperature too. We can assume then the volume is constant because the tank is isolated. The tank will be full when pressure will be in equilibrium, that means when pressure will be 1 atm because it is environment pressure. Using the following equation:
P1 /T1 = P2 /T2 and replacing, T2 = P2 *T1 / P1 = 1 atm * 298K / 0.5 atm = 596 K.

Answer:
KCrO₃
Explanation:
26.6% K, 35.3% Cr and 33.0% O
The steps in obtaining the empirical formulae from percentage composition is given as;
Step 1:
Divide the percentage composition by the atomic mass of the elements
K = 26.6 / 39.0983 = 0.6803
Cr = 35.3 / 51.9961 = 0.6789
O = 33.0 / 16 = 2.0625
Step 2:
Divide all though by the smallest number (0.6789)
K = 0.6803 / 0.6789 = 1.002
Cr = 0.6789 / 0.6789 = 1
O = 2.0625 / 0.6789 = 3.038
The Empirical formular is the ratio between the elements. This given as;
KCrO₃
