Question

To identify a liquid substance, a student determined its densityUsing a graduated cylinder, she measured out a 45 sample of the substance. She then measured the mass of the sample, finding that it weighed 38.5 g. She knew that the sub stance had to be either isopropyl alcohol (density 0.785g / m * L ) or toluene (density 0.866g/mL) . What are the calculated den sity and the probable identity of the substance?

Answer 1

(a) calculated density= 0.86 g/mL. The substance is probably toluene, density= 0.866 g/mL (b) 40.4 mL ethylene glycol (c) 1.11 x 10^3 g nickel
