Question

Which of the following compounds contains the largest number of atoms? Select one: O a. 5.0 mol of HBr b.2.0 mol of H2SO4 O c.3.0 mol of NH3 d. 4.0 mol of Kas e. 1.0 mol of CH3COCI

Answer 1

No of molecules × Moles ×Na ; Na - Avogadro number

No of atoms = molecules × atomicity

No of atoms = moles ×Na × atomicity

No of molecules = mol & NA ; NA Avogadro no. NA = 6x 1023 No of atoms = molecules & Atomicity - mol & NAX Atomicity Atomicity present in one No. of atoms molecules - a smd HBr molaNAx atomicing - 5 NAX2 atoms = 10 NA atoms. (6) amol H₂SO4 → 2X NAX7 atoms → 14 NA atoms, (c) 3 mol NH 3xNAx4 aloms - 14NA atoms. (d) 400 ks 4X NAX 3 atoms 12 NA atoms le lomol th Coco - - 10xNAX 7 atoms TONA atoms.
