<span>Charles' law says "at a constant pressure, the volume of a fixed amount of gas is directly proportional to its absolute temperature".
V </span>α T
Where V is the volume and T is the temperature in Kelvin of the gas. We can use this for two situations as,
V₁/T₁ = V₂/T₂
V₁ = 2.00 L
T₁ = 40.0 ⁰C = 313 K
V₂ = ?
T₂ = 30.0 ⁰C = 303 K
By applying the formula,
2.00 L / 313 K = V₂ / 303 K
V₂ = (2.00 L / 313 K) x 303 K
V₂ = 1.94 L
Hence, the volume of the balloon at 30.0 ⁰C is 1.94 L
5 mols = 100 grams
1 mol = 100/5
1 mol = 20 grams.
Notice that in the equation given, there is 1 mol of Mg3N2
and 6 mol of H2O. Consequently, the question is requesting, if we took 2.5 mol
of Mg3N2, how many mol of H2O would be essential to complete a similar reaction
-- in quintessence, multiplying everything by 2.5:
the solution would be: 6 * 2.5 = 15 mol
