Question

If the atomic mass of sodium is 23,the number of moles in 46gram of sodium is

Answer 1

No of moles of Na = mass of Sodium/ molar mass 1) frist we have to divide mass of Na w.r.t molar mass of Na #) molar mass of Na =23 gm/mol

Answer 2

no of moles = given weight /gram Aaronic weight

= 46/23

= 2 moles

therefore the no.of moles in 46grams of Na is 2 moles
