(adsbygoogle = window.adsbygoogle || []).push({}); 1. The molecular weight of NaCl is 58.54. A 1 M solution of NaCl has 58.54 g NaCl dissolved in distilled water to a total volume of 1000 mL or 1 L. a .1 M solution has .854 g/L. A .2 M solution has 11.71 g/L.

Qustion 1 - What is the molarity of a 5% w/v NaCl solution?

Question 2 - What is the percent concentration of a 2M NaCl solution?

Question 3 - The molecular weight of glucose is 180.16. Describe how you would make up 100 mL of a .5M solution.

2. The only equation I have come up with is Molarity*Volume = grams/molecular weight. But I have no clue if that is relevant or what to do with it.

3. All I have been able to do is verify what the information gives me such as:

1 x 1 = 58.54/58.54

.1 x 1 = 5.84/58.54

.2 x 1 = 11.71/58.54

But I don't know where percentage comes into this at all. I haven't been able to find any examples on the internet that show me how to even begin solving these questions.
