Explanation:

Formula for density:

Density = mass/volume

p = m/v

Let's substitute the given values into the equation:

p = m/v

p = 23.2/8.593

Solve:

p = 23.2/8.593

p = 2.69987198883

2.69987198883 grams per volume

Notice that 2.69987198883 is the exact answer. Your answer is 2.67, which is inaccurate, even if rounded. If you were to round the exact answer to the nearest hundredth, it would be 2.70 which is not 2.67.

Therefore, your friend gave the better response because it is the correct answer.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
