Answer : If in any reaction ΔH (fusion) is given we can consider its units;

ΔH (transition) has units (KJ/mol) and mass and molecular mass of that compound has unit mol/g and g respectively.

When we solved this, we get the units as KJ/mol which satifies the equation value for q.

So, q=n X ΔH (transition);

Hence, to find the mass of solid we can use the above equation.
