An empty vessel has with mass 5 kg with volume 0.1 m^3, is now completely filled with a liquid of density 100 kg/m^3, what is the final density of the cylinder?(a) 50 kg/m^3(b) 100 kg/m^3(c) 150 kg/m^3(d) 200 kg/m^3This question was addressed to me by my school principal while I was bunking the class.My question comes from Density topic in division Moles, Density & Concentration of Basic Chemical Engineering |

Answer» RIGHT CHOICE is (c) 150 kg/m^3 Easiest explanation: MASS of LIQUID = 100*0.1 = 10 kg, => total mass of cylinder = 10 + 5 = 15 kg, => FINAL density of liquid = 15/0.1 = 150 kg/m^3. |
