Moles of NAF are in 34.2 grams of a 45.5% by mass naf solution 15.6 g
One mole is the Avogadro number of particles (atoms, molecules, ions, or electrons) in a substance. One mole of atoms contains 6 x 1023 atoms. The 6.022 x 10 23 number is known as the number of Avogadro or the constant of Avogadro.
For the conversion of mass and number of particles, the definition of the mole can be used.
A mole is the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12 percent by mass = mass solute x 100 / mass solution percent mass = 45%mass of solution = 34.2 g
substituting the value,
45.5 % = mass solute NaF x 100 / 34.2 mass solute NaF
= 34.2 x 45.5 /100=15.6 g
Therefore, the total number of moles that are participating will be 15.6 g
