Question

Calculate the mass of 0.25 mol of sodium chloride, NaCl.

Answer 1

Answer:

to solve quick

0.25×2= 0.5

So, one mole of NaCl weighs 58.44 g. A 2.5 M solution is 2.5 moles per liter (Molarity is just the number of moles per liter). Therefore, 0.5 L would contain 1.25 mol. Hence, you would need 1.25 × 58.44 g = 73

now half it 36.5g
