Question

a substance has a mass of 1.50 lb (1 lb = 453.59g) and volume of 1.25l. what is its density in g/ml?:

1. 0.544 g/ml
2. 544 g/ml
3. 54.4 g/ml
4. 544308 g/ml

Explanation:

Step1: Convert mass to grams

Given mass is \(1.50\) lb, and \(1\) lb \( = 453.59\) g. So mass in grams is \(1.50\times453.59 = 680.385\) g.

Step2: Convert volume to milliliters

Volume is \(1.25\) L, and \(1\) L \( = 1000\) mL. So volume in mL is \(1.25\times1000 = 1250\) mL.

Step3: Calculate density

Density formula is \(
ho=\frac{m}{V}\), where \(m\) is mass and \(V\) is volume. Substituting values: \(
ho=\frac{680.385}{1250}=0.544308\approx0.544\) g/mL.

Answer:

1. 0.544 g/mL
