Briefing

mass = number of moles * molar mass

molecular weight of methyl salicylate is 152.1 g/mol

number of moles = 2 mmol = 0.002 moles

mass = 0.002 moles * 152.1 g/mol

mass of methyl salicylate = 0.3042 g

Volume is determined from the density and mass

Volume = mass/density

volume of methyl salicylate = 0.3042 g/ 1.174 g/ml

volume of methyl salicylate = 0.259 mL
