Answer:
61.9mL
Explanation:
Given parameters:
Initial volume = 49.7mL
Initial temperature = 20°C = 293K
Final temperature = 92°C = 365K
Unknown:
Final volume = ?
Solution:
To solve this problem, we simply apply the Charles's law which states that "the volume of a fixed mass of a gas varies directly as it absolute temperature if the pressure is constant";
V and T are volume and temperature values
1 and 2 are initial and final states
Now insert the parameters and solve;
=
V2 = 61.9mL
Answer: 0.407 moles of aluminum chloride could be produced from 11.0 g of aluminum.
Explanation:
To calculate the moles :
According to stoichiometry :
is the limiting reagent as it limits the formation of product and
is the excess reagent.
As 2 moles of give = 2 moles of
Thus moles of give =
of
Thus 0.407 moles of aluminum chloride could be produced from 11.0 g of aluminum.
