Determine the number of moles present in 0.55mg of electrins |
| Answer» PLEASE MARK ME AS BRAINLIEST Explanation:Mass of one ELECTRON = 9.1 * 10^-31 kg TOTAL NUMBER of electrons in 0.55 * 10^-6 kg = 0.55 * 10^-6 / (9.1 * 10^-31) = 6 * 10^23 electrons 1 mol of electrons = 6 * 10^23 electrons. Therefore no. of moles of electrons present in 0.55mg of electrons is nearly 1. | |
