Question

hello maam/sir, kindly help me with this numbers please... kindly provide complete solution.. I PROMISE to give 5 star rating directly

7. Calculate the molarity of each of the following solutions: (a) 6.57 g of methanol (CH,OH) in 1.50 x 10' ml of solution, (b) 10.4 g of calcium chloride (CaCl,) in 2.20 x 10' ml of solution, (c) 7.82 g of naphthalene (CoHa) in 85.2 mL of benzene solution 8. You have 505 ml of a 0.125 M HCI solution, and you want to dilute it to exactly 0.100 M. How much water should you add? Assume volumes are additive. 9. A 35.2-ml, 1.66 M KMNO, solution is mixed with 16.7 ml of 0.892 M KMNO, solution. Calculate the concentration of the final solution.
