Which has the highest mass ? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

a) 50g of Iron (Given) b) 5 moles of 2 N 1 mole of 2 N weights 28g 5 moles of 2 N will weight = 5 28 140g x c) 0.1 mole of Ag 1 mole of Ag weighs 108g 0.1 mole of Ag will weigh= 0.1 108 10.8g x d) 23 10 atoms of C 1 mole i.e. 23 6.023 10 x of C weigh 12g 23 10 atoms of C will weigh 23 23 10 12 6.023 10 g x x 1.99 2g The correct option is (b) Note:-weight in g= moles xAt. wt. or molecular weight 23 6.023 10 number of atomsor molecules x x At. wt. or mol.wt.
