Acylinder of iron has a mass of 23.45 g. if it is placed on an electronic balance that reports all masses 18.00% too low due to miscalibration, what mass will the balance report for the cylinder of iron?

For the answer to the question above asking what mass will the balance report for the cylinder of iron if a cylinder of iron has a mass of 23.45 g. If it is placed on an electronic balance that reports all masses 18.00% too low due to miscalibration,
A cube has a volume of 8.0 cm3 and a mass of 21.6 grams
Using an electronic analytical balance of graduated cylinder.
The density of iron is 7.87 g/mL.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
