You have 28.5 g of iron shot that has a volume of 3.60 mL. From this information, calculate the density of iron.

laila [671]

Answer:

$\boxed {\boxed {\sf \rho \approx 7.917 \ g/mL}}$

Explanation

Density can be found by dividing the mass by the volume.

$\rho=\frac{m}{v}$

We know the iron sheet has a mass of 28.5 grams and the volume is 3.60 milliliters.

$m= 28.5 \ g \\d= 3.60 \ mL$

Substitute the values into the formula.

$\rho=\frac{28.5 \ g}{ 3.60 \ mL}$

Divide.

$\rho = 7.91666667 \ g/mL$

Let's round to the nearest thousandth.

The 6 in the ten-thousandth tells us to round the 6 to a 7.

$\rho \approx 7.917 \ g/mL$

The density of iron is about <u>7.917 grams per milliliter.</u>
