Question

What is the density of an unknown compound in g/ml if 1.28 pounds of the compound has a volume of 4.50L

Answer 1

First, we need to convert the mass of the compound from pounds to grams:
1.28 pounds * 453.59 grams/pound = 580.61 grams

Next, we can use the formula for density:
Density = Mass / Volume

Density = 580.61 grams / 4.50 L

Density = 128.91 g/L

Therefore, the density of the unknown compound is 128.91 g/L or 0.12891 g/mL (since there are 1000 mL in 1 L).
