Calculate the molarity of solution containing 0.5g of Naoh dissolved i

1.	Calculate the molarity of solution containing 0.5g of Naoh dissolved in 500cm³
Answer» Answer: Explanation: 1 mol NaOH = atomic MASS of Na + atomic mass of O + atomic mass of H = 23 + 16 + 1 = 40g. 0.5 g NaOH = 0.5 / 40 mol NaOH = 0.0125 mol of NaOH 500 ml of water = 500/1000 = 0.5 L Now, MOLARITY = NUMBER of MOLES of solute / total VOLUME of the solvent = 0.0125 / 0.5 = 0.025 mol/L. thank you

Calculate the molarity of solution containing 0.5g of Naoh dissolved in 500cm³

Answer»

Answer:

Explanation:

1 mol NaOH = atomic MASS of Na + atomic mass of O + atomic mass of H = 23 + 16 + 1 = 40g.

0.5 g NaOH = 0.5 / 40 mol NaOH = 0.0125 mol of NaOH

500 ml of water = 500/1000 = 0.5 L

Now, MOLARITY = NUMBER of MOLES of solute / total VOLUME of the solvent

= 0.0125 / 0.5 = 0.025 mol/L.

thank you
