1245 liters because you move the decimal place over to the right six times
Answer:
0.5M is the answer.
Explanation:
1M solution is the solution containing 1mole solute dissolved per litre of solution.
Using unitary method,
1000cc gives 1M.
1cc gives 1/1000M.
500 cc gives 500/1000M=0.5M
The original concentration of the acid solution is 6.175
10^-4 mol / L.
<u>Explanation:</u>
Concentration is the ratio of solute in a solution to either solvent or total solution. It is expressed in terms of mass per unit volume
HBr + NaOH -----> NaBr + H2O
There is a 1:1 equivalence with acid and base.
Moles of NaOH = 72.90
10^-3
0.25
= 0.0182 mol.
[ HBr ] = moles of base / volume of a solution
= 0.0182 / 29.47
= 6.175
10^-4 mol / L.
