Question

How are 0.50 mol Na2CO3 and 0.50 M Na2CO3 different?

Answer 1

Explanation:

0.5 mol Na2CO3 means 0.5 moles of Na2CO3 while 0.5 M means a 0.5 molar solution of Na2CO3 .

0.5 moles of Na2CO3 simply refers to 0.5 × (106) = 53 g of Na2CO3

0.5 M of Na2CO3 solution on the other hand, tells us that we have been given an aqueous solution with 0.5 moles = 53 g of Na2CO3 per 1000mL of the solution
