Answer:
First calculate the molar mass of NaCl using atomic weights in the periodic table.
atomic weight of Na is 23
atomic weight of Cl is 35.5
adding this will give _____
What this means is 1 mol of NaCl weighs 58.5 g.
The question is how many mols would weigh 30 g.
30 g × 1mol/ 58.5 g = 0.512 moles
