Best ResponseYou've already chosen the best response.0The formula is m=cv Where m is the mass that you are determining, c is the concentration in this case 0.512M and v is volume (note volume is in litres so you would have to convert it)

Best ResponseYou've already chosen the best response.0100mL=0.1L m=cv =(.512)(.1) =0.0512g

Best ResponseYou've already chosen the best response.0but we're trying to make a 100mL solution of 0.512g how is the answer the same as the number in the question with one more 0???

Best ResponseYou've already chosen the best response.0Because it's 100mL solution (or 0.1L) it would change more if it was at a different volume like if it was at 200mL you would have 0.102g of NaCl in it

Best ResponseYou've already chosen the best response.0So is the answer 2.99?

Best ResponseYou've already chosen the best response.0What I did was (0.1L x 58.4 x 0.512) because there is 58.4 g/mol in NaCl

Best ResponseYou've already chosen the best response.0You don't need to put the molar mass in at all Let's say if you did put in 2.99g of NaCl c=m/v =2.99/0.1 =29.9 as your concentration
