Answer:
0.175mol
Explanation:
Molarity of a solution can be calculated thus:
Molarity (M) = number of moles (n) / volume (V)
According to the information provided in this question, volume of NH4OH = 0.125L, molarity = 1.4M
Using; Molarity = n/V
1.4 = n/0.125
n = 0.175mol
First write out the eqn, and balance it.
next, take 12.8g/mr of aluminium
this will give u the mols of aluminium
next, take the ratio of HCL and Al, compare and find the mols of HCL.
take the mols of HCL/mr of HCL to give u mass

Answer:
See explanation
Explanation:
A limiting reactant is the reactant in a reaction that is done reacting first, because there are less moles of it than are needed for a full reaction with the other compound or compounds.
Hope this helps!
