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 %

Answer:
78.75g
Explanation:
The density of diamond is the mass of diamond per unit of its volume. The density of a substance is calculated using the formula:
Density (g/cm^3) = mass (g) / volume (cm^3)
According to the question, the density of diamond= 3.15g/cm^3, volume of diamond= 25cm^3, mass = ?
Hence, to calculate the mass, we say;
Mass = Volume × density
Mass = 25 × 3.15
Mass = 78.75
Therefore, the mass of diamond is 78.75grams.
