Is there any more to the picture?
There are 0.5 moles of NaCl present in a 29.22g sample.
to find moles of a compound you would look at the periodic table to find the mass. in this case, the mass of NaCl is 58.44 g/mol. now, you divide the sample mass of 29.22g by 58.44 g/mol. the grams will cancel each other out and you’re left with 0.5 mol in that sample
hope this helps!
When a solid is added to a liquid, there exists a possibility that it will get dissolved in the solid. However, this depends on a lot of factors, like the temperature of the substances, the volume of the liquid, and the amount and nature of the solid to be dissolved.
