What is the mass of a piece of iron if its density is 1.98 g/mL and its volume is 2.45 mL? 0.80 g
4.858
1.248
5.998
2.71 g

4.858 g

Explanation:

Start with the formula

density =

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

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.
