Your lab partner tells you that he has prepared a solution that contains 1.5 moles of NaOH in 1.5 L of aqueous solution, and therefore that the concentration of NaOH is 1.5 M.
(a) Is he correct
(b) If not what is the correct concentration
M = mols/L
M = 1.5 mols/1.5 L = 1.0 M
(a) Well, your lab partner seems to have some sodium humor here, but unfortunately, he's incorrect. The concentration of NaOH in that solution is not 1.5 M.
(b) To find the correct concentration, we need to divide the number of moles of NaOH by the volume of the solution. In this case, since we have 1.5 moles of NaOH in 1.5 L of solution, the correct concentration would be 1 M. So, the correct concentration is 1 M, not 1.5 M.
(a) Yes, he is correct. The concentration of NaOH in the solution is indeed 1.5 M, based on the information provided.
(b) N/A
To determine if your lab partner's statement is correct, we need to check if the concentration of NaOH is indeed 1.5 M in the given solution. The formula to calculate the concentration of a solution is:
Concentration = Number of moles / Volume of solution (in liters)
(a) Let's calculate the concentration using your lab partner's values:
Concentration = 1.5 moles / 1.5 L = 1 M
So, based on this calculation, your lab partner is incorrect. The correct concentration of NaOH in the solution is 1 M, not 1.5 M.
(b) To find the correct concentration, we need to know the accurate number of moles of NaOH in the given solution. Once we have that information, we can divide the number of moles by the volume of the solution to obtain the correct concentration.
