Firstly you need to understand that silver mirror test is only given by aldehydes in order to give an acid hence the answer should be a primary alcohol which on oxidation with PCC(pyridium chromyl chloride) will give you an aldehyde
112/22400ml=0.005 moles of the methyl compound
now we can find the molecular weight of the compound by the formula
moles=weight/mol weight
mol.wt=0.44/0.005=88g
b)5(C)+(O)+12(H)=12×5+16+12×1
=88g
I hope this helps
