Question

What is the mass of a piece of iron if its density is 1.98 g/mL and its volume is 2.45 mL?

Answer 1

Answer:

4.858 g

Explanation:

Start with the formula

density = $\frac{mass}{volume}$

density = 1.98 g/mL

volume = 2.45 mL

mass = ??

rearrange the formula to solve for mass

(density) x (volume) = mass

Add in the substitutes and solve for mass

1.98 g/mL x 2.45 mL = 4.858 g
