Density of a substance is given by dividing its mass with volume.
The volume of the block is 3.5 cm× 2.0 cm ×1.5 cm = 10.5 cm³
thus density = 34.56 g/ 10.5 cm³
= 3.291 g/cm³
The answer would be C. CH3COOH, deprotonated

The relative mass of an electron is 1/1840 the mass of a C-12 atom. Hence, option B is correct.
<h3>What is an electron?</h3>
An electron is a negatively charged subatomic particle.
An electron is very small, about 1/1,837th the mass of a proton. Atomic Weights Atomic mass of an atom is expressed in atomic mass units (amu) which are approximately grams. A more conventional way of expressing the mass of an atom is Atomic Weight.
Atomic mass units are expressed relative to the atomic mass unit of an unbound neutral carbon-12 atom.
Hence, the relative mass of an electron is 1/1840 the mass of a C-12 atom.
