Question

a sample of iron ore with a volume of approximately 250 cubic centimeters has a weight of 1000 grams. which of the following best approximates the density of the iron ore, in grams per cubic centimeter? 5 of 7 question ○ 4.0 g/cm³ ○ 0.25 g/cm³ ○ 0.4 g/cm³ ○ 2.5 g/cm³

Explanation:

Step1: Recall the density formula

Density formula is \(d=\frac{m}{V}\), where \(m\) is mass and \(V\) is volume.

Step2: Substitute the given values

Given \(m = 1000\) grams and \(V=250\) \(cm^{3}\). Then \(d=\frac{1000}{250}\).

Step3: Calculate the value

\(\frac{1000}{250}=4\)

Answer:

A. \(4.0\ g/cm^{3}\)
