How many molecules of lactic acid C3H6O3 are in 1 L of a 0.5 M solution?

Answer 1

There is half a mole of lactic acid, 45 grams, which is half of the molecular weight. If you actually want to know the number of molecules; it is half of Avogradro's number which is 6.02 X (multiplied by) one followed by 23 zeros.

Answer 2

In a 0.5 M solution of lactic acid (C3H6O3), the concentration is 0.5 moles per liter. This means there are 0.5 moles of lactic acid molecules in 1 liter of the solution. Using Avogadro's number (6.022 x 10^23), we can calculate that there are approximately 3.011 x 10^23 molecules of lactic acid in 1 liter of a 0.5 M solution.

Answer 3

12x3+6+16x3=90

Molar mass of lactic acid is 90

Morality= number of grams/ molar mass in 1000 ml

No. of grams present= 0.5x90 answer = 45 g

Answer 4

dhjghj Use the formula

Answer 5

45 grams
