One cup of fresh orange juice contains 124 mg of ascorbic acid (vitamin c, c6h8o6). given that one cup = 236.6 ml, calculate the molarity of vitamin c in organic juice.

The formula for calculating molarity is moles of solute divided by liters of solution, thus the unit of molarity is moles/liter (M/L). To calculate molarity find the number of moles of solute and the volume of solution in liter.
To solve the problem above, convert 118 mg of vitamin c to mole. To do this first find the molar mass of vit c from its structural formula given above:
molar mass of vit c = (12*6)+ (1*8)+ (16*6) = 176.
moles of vit c = 118mg C6H8O6 * (1 mol of C6H8O6/176mg of C6H8O6)
Mole of vit c = 0.67moles
convert 225.2ml to liter = 225.2/1000 = 0.2252.
molarity = 0.67/.2252 = 2.9M. i hope this helps :)

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
