What volume of iron (blue/purple line) would have a mass equal to a piece of lead (red line) that has a volume of 3.0 mL? A.
40 mL

B.
40 g

C.
4.9 g

D.
4.9 mL
I NEED HELP PLS

4.3 g

Explanation:

Step 1: Given data

Volume of the piece of Pb: 3.0 mL

Step 2: Calculate the mass of the piece of Pb

The density of Pb is 11.35 g/mL.

3.0 mL × 11.35 g/mL = 34 g

We will look for the volume of a piece of Fe with a mass of 34 g.

Step 3: Calculate the volume of a piece of 34 g of Fe

The density of Fe is 7.87 g/mL.

34 g × 1 mL/7.87 g = 4.3 g

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
