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

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
