lhghYuAlZLqutHiR18WodKAMFIER-TFHKG7oOCi1.cehwmh5VROvgKFhw/7NgH-Xaq1ow deniflying errors in the soluion to a besic quanthative problem Study the probiem and proposed solution below. Is the final answer correct? Then dick the No mistakes button. Is the final answer wrong? Then dick the button in front of the line with the first mistake and correct the matake. Wote: don't worry about corecting the rest of the solution, after the first mistake The density of a pure substance is its mass per unit volume. The density of ethylene glycol has been measured to be lon.Caeulate the mass of 55, of ethylene glycol Be sure your ansser has a unit symbol and the correct number of signéicant | Solution wnite down the definition of density Solve for mass 55. 10975 Put in the data given " SO 14, Use the celculetor Round to the correct number of significent digts.Explanation / Answer
Density is mass hiven divided by volume of the substance.
Density of ethylene glycol given is 1097g/L. First we need to convert this into ml.
1L=1000ml so divide the density by 1000.
Density= 1.097g/ml
Volume=55ml
Density=mass/volume
So, mass= density × volume
= 1.097×55
mass= 60.355g
The final answer in the proposed solution is incorrect. The mistake is in the very first step. Formula of density is wrong.
