The number of moles of 210 grams of NaHCO₃ is 2.5 moles.
To calculate the number of moles use the formula
Number of moles = [tex]\frac{\text{Given Mass}}{\text{Molar Mass}}[/tex]
Mass of NaHCO₃ = 210 g
Now we have to find the Molar mass of NaHCO₃
= Atomic mass of Na + Atomic mass of H + Atomic mass of C + 3 (Atomic mass of O)
= 23 + 1 + 12 + 3 (16)
= 36 + 48
= 84 g/mol
Now put the value in above formula we get
Number of moles = [tex]\frac{\text{Given Mass}}{\text{Molar Mass}}[/tex]
= [tex]\frac{210\ g}{84\ g/mol}[/tex]
= 2.5 moles
Thus from the above conclusion we can say that The number of moles of 210 grams of NaHCO₃ is 2.5 moles.
