In order to prepare 75% medical alcohol for disinfection, students need to use a measuring cylinder to measure 100g pure alcohol with a density of 0.8g/cm ^ 3 at a time. They should choose ↓ of the measuring cylinder The range and division values are () A.50ml;5ml B.100ml;2ml C.250ml;5ml D.400ml;10ml

V = m / P = 100 / 0.8 = 125cm ^ 3, so choose C
