Answer:

0.895 g/mL

Explanation:

Step 1: Given data

Mass of liquid Z (m): 2.763 lb

Volume of liquid Z (V): 5.93 cups

Step 2: Convert "m" to grams

We will use the relationship 1 lb = 453.59 g.

2.763 lb \times \frac{453.59 g}{1lb} = 1,253g

Step 3: Convert "V" to milliliters

We will use the relationship 1 cup = 236.59 mL.

5.93cup \times \frac{236.59mL}{1cup} = 1.40 \times 10^{3} mL

Step 4: Calculate the density of the liquid Z

The density (ρ) of the liquid Z is equal to its mass divided by its volume.

\rho = \frac{m}{V} = \frac{1,253g}{1.40 \times 10^{3}mL  } = 0.895 g/mL
