Question

35 ml of ethyl alcohol (density = 0.789 g/ml) is added to a graduated cylinder that weighs 44.28 g. What will be the mass of the cylinder plus the alcohol?

A. 35.00 g
B. 44.28 g
C. 79.78 g
D. 79.78 g

Answer 1

To find the mass of the cylinder plus the alcohol, we need to add the mass of the alcohol to the mass of the cylinder. The mass of the cylinder plus the alcohol is 71.895 g.

Step-by-step explanation:

To find the mass of the cylinder plus the alcohol, we need to add the mass of the alcohol to the mass of the cylinder. The mass of the alcohol can be calculated by multiplying the volume of the alcohol by its density:

Mass of the alcohol = Volume of the alcohol * Density of the alcohol

= 35 ml * 0.789 g/ml = 27.615 g

Next, we add the mass of the cylinder (44.28 g) to the mass of the alcohol to find the total mass:

Total mass = Mass of the cylinder + Mass of the alcohol

= 44.28 g + 27.615 g = 71.895 g

Therefore, the mass of the cylinder plus the alcohol is 71.895 g. The answer is not given in the options provided.
