So for question one the answer is 50/58.54 M, which is .854 M.
For question two, I did (117.08 x 100)/1000 and got 11.7%.
For the third question I did:
(100/1000)*(.5) = x/180.16
and got 9 grams(?). So would that mean dissolving 9 grams of glucose in the 100 mL of solution? Or am I...
Sorry, yes it is 5.854 g/L.
For the first question would the answer be .08 M then? The second question confuses me though...I get 117.08 as the answer but how does that make sense as a percentage?
And for whatever reason I've got to do this worksheet for my biology class...I'm not sure why...
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...
