Question

calculate the density of the red mystery substance. instructions: 1. mass the empty graduated cylinder. 2. calibrate the balance to 0g. 3. pour the liquid into the graduated cylinder. record the mass. 4. measure the volume of the liquid in the graduated cylinder. record it. 5. calculate the density of the liquid by dividing the mass by the volume. mass = g volume = ml density = g/ml

Explanation:

Step1: Determine the mass

The mass of the liquid - filled cylinder is 41.1 g. But we need the mass of just the liquid. Since we are not given the mass of the empty cylinder, assume the mass reading is of the liquid only. So Mass = 41.1 g.

Step2: Determine the volume

From the graduated - cylinder, the volume of the liquid is read as V = 25 mL (the meniscus is at 25 mL mark).

Step3: Calculate the density

Use the density formula $
ho=\frac{m}{V}$. Substitute m = 41.1 g and V = 25 mL. $
ho=\frac{41.1}{25}=1.644$ g/mL.

Answer:

Mass = 41.1 g
Volume = 25 mL
Density = 1.644 g/mL
