change 270.0ml into litres, 270.0/1000L=0.27
moles of solute= molarity* litres
0.600M*0.27L=0.162
calculate molar mass of ethyl alcohol =46.06844
1 mole= 46.06844
0.162= ?
so, 46.06844*0.162= 7.46g
the answer is 7.46g

∙ 10y ago1. take 270.0 ml and convert into Liters
so, 270.0 ml/1000 ml = 0.270 Liters
2. Use Molarity equation to find your moles of solute. (M=moles/L)
so, change equation to moles=M*L 0.1755moles=(0.650M)*(0.270L)
3.now use molar mass to calculate grams (molar mass=moles/grams)
so, change equation to grams=(moles)/(molar mass)
0.000992grams=(0.1755moles)/(177molar mass)
