Answer #1

moles of ethanol = 0.000534 mol

molar mass of ethanol = 46.07 g/mol

mass of ethanol = moles x molar mass

                          = 0.000534 x 46.07

                           = 0.0246 g

density = 0.78 g /ml

density = mass / volume

0.78 = 0.0246 / volume

volume of ethanol = 0.0315 mL

Note : here total solution volume is not given
