Calculate the molarity of a solution containing 2.80 moles of ethyl alcohol (C2H6O) in
500 mL of solution.
Molarity = n/V = 2.8 moles/0.5L = 5.6 mol/L = 5.6 M

1. An experiment requires a solution that is 80% methyl alcohol by volume. What volume of methyl alcohol should be added to 200 mL of water to make this solution?
Solution:The percentage of CH3OH by volume is defined as:ϕCH3OH = [VCH3OH / (VCH3OH + VH2O)] × 100%Hence,ϕCH3OH / 100% = VCH3OH / (VCH3OH + VH2O)80% / 100% = VCH3OH /...

Calculate the mass of ethyl alcohol which must be dissolved in 750 grams of water to make 0.5m solution. Full solution.
Сm = n(solute)/m(solvent)n=m/MM(C2H5OH)=46 g/moln(C2H5OH)=0.5x0.75=0.375 molm(C2H5OH)=0.375 x 46 = 17.25 g

a water solution contains 10% ethyl alcohol by mass and has a density of 0.983 g/cm3 . what is the mass of ethyl alcohol is present in 7.5 L of this solution
7.5L = 7.5*1000 mL mass of 7.5 L solution: 7.5*1000 mL * 0.983 g/cm 3 = 7.3725*1000 g mass of ethyl alcohol: 7.3725*1000 g * 0.1 = 737.25 g Answer:...
