Best ResponseYou've already chosen the best response.0find the amount of moles using the formula for molarity: Molarity = moles/Liters of solution then multiply the number of moles by avogadros number

Best ResponseYou've already chosen the best response.0ps. convert to mM to M. 1 mM = 0.001 M

Best ResponseYou've already chosen the best response.0so calculate the mass C6H12O6? then divide that by 1.02?

Best ResponseYou've already chosen the best response.0no, you don't need the molar mass since you're not converting to grams

Best ResponseYou've already chosen the best response.0i'm just lost on the moles then how do i find that

Best ResponseYou've already chosen the best response.0with the molarity and the volume of solution given

Best ResponseYou've already chosen the best response.0molarity is a form of expressing concentration (in terms of moles per liter).. so basically by multiplying the molarity by the volume, you find the moles but you have to covert to molarity because mM meaning millimolar, 1 molar = 0.001 millimolar

Best ResponseYou've already chosen the best response.0so like \[\frac{ 2mL }{ 1mm} X \frac{ 1mm }{ 0.001 } ?\]

Best ResponseYou've already chosen the best response.0nope convert volume to liters .. 2mL = 0.002 L convert millimolarity to molarity 1.02 mM = 0.00102 M 0.00102 M x 0.002 L =

Best ResponseYou've already chosen the best response.0looks right, i don't have a calculator around to check though

Best ResponseYou've already chosen the best response.0ps you still need to multiply by avogadros number

Best ResponseYou've already chosen the best response.0yea i figured that I'm trying to get a better number I would take that equations answer 2.04 ... and multiply it by avogadro's number right

Best ResponseYou've already chosen the best response.0yep, it's 2.04x10^4 though don't forget
