Find the number of moles of the following substances 210 grams of NaHCO3
Triss [41]

The number of moles of 210 grams of NaHCO₃ is 2.5 moles.

<h3>How to find the Number of moles ? </h3>

To calculate the number of moles use the formula

Number of moles = \frac{\text{Given Mass}}{\text{Molar Mass}}

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 = \frac{\text{Given Mass}}{\text{Molar Mass}}

                             = \frac{210\ g}{84\ g/mol}

                             = 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.
