Number of atoms in 24 g 02 |
|
Answer» 0.75 * 6.022* 10^23Explanation:As we know To find the NUMBER of ATOMS / molecules we need to find the number of moles first.Number of moles = Given MASS / Molar Mass of ATOMIC mass --------(1)So the molar mass of O = 16hence the molar mass of O2 = 16*2= 32Applying this in (1)We GET,Number of moles= 24/32 =0.75 So therefore the number of atoms of O2 = Number of moles * Avagadros number = 0.75 * 6.022* 10^23Hope this helps... |
