In order to measure alcohol with a density of 0.8 × 103kg / m3 and a mass of 100g at a time, there are four kinds of measuring cylinders to choose from. Which one do you think is more suitable () A. The measuring range is 50ml B, 100ml C, 250ml D and 1000ml

The volume of alcohol is: v = m ρ = 100g0.8g/cm3 = 125cm3 = 125ml; the volume of alcohol in a and B is beyond its range, so it can't hold alcohol; the volume of alcohol in C and D can hold alcohol, but the range in D is too large, so the cylinder in C is used instead of the cylinder in D
