An unknown weight of the aluminum sample (Al) was placed in the hydrobromic acid solution. The reaction was as follows: 2 Al (s)

Question

An unknown weight of the aluminum sample (Al) was placed in the hydrobromic acid solution. The reaction was as follows:
2 Al (s) + 6 HBr (aq) -> 2 AlBr3 (s) + 3 H2(g)
What was the mass of the Al sample (in grams) if a 14.4 L of the gas product of this reaction was collected at the temperature of 520.0°C and
under the pressure of 741 mmHg?
Molar masses (in g/mole): Al = 26.98; HCI=80.91; AICI3 = 266.69;H₂=2.00
Guiding questions:
The temperature in K was
The pressure in atm was
The number of moles of gas was
The mass of the Al sample was
