Answer 1

moles / L = molarity

Answer 2

I know that. I just don't know how to put it into a equation to work out. :/

Answer 3

Molarity = number of moles of solute/volume of solution in liter
find the number of moles of solute that is 450.0 g of C6H12O6

Answer 4

Molarity = numlber of moles/volume in liters...
given that 450g of C6H12O6 is present in 2.50 x 10^2Cm3...
1cm3 = 0.001liters
then 2.50 x 10^2 cm3 = ?liters
thus, 2.50 x 10^2cm3 = 0.25liters
number of moles = given weight/molecular weight
molecular weight of C6H12O6 = 180.1559g/mol
number of moles = 450/180.1559 = 2.4978moles...
thus, molarity = 2.4978/0.25 = 9.99M....

Answer 5

Thank you. (: I'm sure I'll figre the rest out.

Answer 6

lol nothing to figure out :P

Answer 7

How do you delete questions if you didn't mean to post them?

Answer 8

i have figured out all the thing... there is nothing to work out by U.....
