Answer:
The balance of chemical equation is given below.
3Ca + N2------ Ca3N2
The question is partially incorrect, because nitration of <span> methyl benzoate results in generation of methyl 3-nitrobenzoate, and not methyl 2-benzoate.
This a because of the present of ester group, which deactivated benzene ring at ortho and para position. Due to this, the electrophile (NO2+) attackes on meta position.
The detailed mechanism is attached below.</span>
Mass = molecular mass x mol
mass = 176.128 x 0.000142
mass = 0.025 g (3 s.f)
By weight the hydroxides are 45.9% of the weight
