A sample of metal has a mass of 24.64 g, and a volume of 5.91 mL. What is the density of this metal?

dlinn [17]

Answer:

$\boxed {\boxed {\sf 4.17 \ g/mL}}$

Explanation:

We are asked to find the density of a metal. Density is the mass per unit volume. It is calculated by dividing the mass by the volume.

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

The mass of the metal sample is 24.64 grams and the volume is 5.91 milliliters. We can substitute these values into the formula.

m= 24.64 g
v= 5.91 mL

$\rho=\frac{24.64 \ g }{5.81 \ mL}$

Divide.

$\rho= 4.169204738 \ g/mL$

The mass measurement has 4 significant figures the volume measurement has 3 significant figures. Our answer for density must match the least number of significant figures, which is 3.

For the number we calculated, that is the hundredth place. The 9 in the thousandth place tells us to round the 6 up to a 7.

$\rho \approx 4.17 \ g/mL$

The density of this metal is approximately <u>4.17 grams per milliliter.</u>

Consider the densities of the

serious [3.7K]

The Percent error in the calculation of densities of the metal during experiment is 0.03 %

<h3>What is Percentage error?</h3>

Percent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage.

Percent error = [Experimental value - Theoretical value] / Theoretical value x 100%

Percent error = 7.83 -7.86 / 7.86 x 100

= 0.03 %
