How to measure 100g alcohol without balance and measuring cylinder?


Because the density of alcohol is 0.8g/ml
Therefore, the volume of 100g alcohol is v = m / ρ = 100g / 0.8g/ml = 125ml
Therefore, if 125ml alcohol is accurately measured with a measuring cylinder, it is 100g alcohol



Don't use a balance, just a measuring cylinder, can you produce 100g alcohol?


p=m/v
∴v=m/ρ=100g÷0.8 g/cm3 =125cm3=125ml
Measure 125ml alcohol out of the measuring cylinder
