How many moles of NaHCO3 are there in a 3g tablet of Alka-Selzer?

Sagot :

We then need to find the molecular weight of sodium bicarbonate (NaHCO 3), which comes out to 84g/mol. To find the number of moles of sodium bicarbonate, we divide the mass of sodium bicarbonate in the tablet (1.916g) by the molar mass (84g/mol). This gives us 0.0228 moles of sodium bicarbonate in one tablet.
