Answer: 778 ml
Explanation:
To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus volume the gas occupy at 30.0°C is 778 ml

Answer:
Mass of hydrogen gas produced = 0.2 g
Explanation:
Given data:
Number of moles of Mg = 0.2 mol
Number of moles of HCl = 0.2 mol
Mass of hydrogen gas produced = ?
Solution:
Chemical equation:
Mg + 2HCl → MgCl₂ + H₂
Now we will compare the moles of of hydrogen with Mg and HCl.
Mg : H₂
1 : 1
0.2 : 0.2
HCl : H₂
2 : 1
0.2 : 1/2×0.2 = 0.1
HCl produced less number of moles of hydrogen gas it will act as limiting reactant.
Mass of hydrogen:
Mass = number of moles × molar mass
Mass = 0.1 mol × 2 g/mol
Mass = 0.2 g
