Question

find the mass of sodium having some no of moles as 5.6g of fe (fe=56u,na=23)​

Answer 1

Given:-

☆Given mass of Fe=5.6g

☆Atomic mass of Fe=56u

☆Atomic mass of sodium=23u

To find:-

☆Mass of sodium have same number of moles as 5.6g Fe

Solution:-

•Molar mass of Fe=56g

•Molar mass of Sodium(Na)=23g

=>Number of moles in Fe:-

=>Given mass/molar mass

=>5.6/56

=>0.1mole

Now,sodium also has same number of moles.

=>Mass=Molar mass×number of moles

=>23×0.1

=>2.3g

Thus,the required mass of sodium is 2.3g
