Calculate the chemical amount of aluminum carbide that is formed by the interaction of aluminum

Calculate the chemical amount of aluminum carbide that is formed by the interaction of aluminum metal with carbon weighing 48 g

m (C) = 48 g.
Let us determine the amount of aluminum carbide substance obtained as a result of the reaction. We write down the equation of reactions.
4Al + 3C = Al4C3
Next, we find the amount of carbon substance. We use the following formula.
n = m / M.
Where n is the amount of substance.
M is the molar mass of the substance.
m is the mass of the substance.
M (C) = 12 g / mol.
n (Al) = 48/12 = 4 mol.
Using the reaction equation, we find the amount of aluminum carbide substance.
4 mol C – x mol Al4C3
3 mol C – 1 mol Al4C3
X = 4 * 1: 3 = 1.33 mol Al4C3.
Answer: n (Al4C3) = 1.33 mol.
