NaBr solution is prepared by dissolving 6.0 g of NaBr in 34.0 ml of H¿O. What is the final concentration of the NaBr solution?

Sagot :

Answer:

1.7133 M

Explanation:

Given:

weight solute = 6.0 g NaBr

volume solution = 34.0 mL H¿O

***note: MW (molecular weight) of NaBr = 103 g/mol

Molarity = [tex]\frac{weight solute}{MW solute (L solution)}[/tex] = [tex]\frac{6.0 g}{103 (\frac{34.0ml}{1000})}[/tex] = 1.7133 mol/L or M
