- 5.01 g of sodium bromide (NaBr) is added to water to create a 500 mL solution. Calculate the molarity of bromine ion in the solution.

 

- The calcium and magnesium concentrations in a water sample are 230.23 mg/L and 110.1 mg/L respectively. Calculate the combined concentration of these compounds in equivalents per liter (eq/L)

*Please solve and show all work for both above (Thank you in advance!)

7. \( 5.01 \mathrm{~g} \) of sodium bromide \( (\mathrm{NaBr}) \) is added to water to create a \( 500 \mathrm{~mL} \) solution. Calculate the molarity of bromine ion in the solution. 8. The calcium and magnesium concentrations in a water sample are \( 230.23 \mathrm{mg} / \mathrm{L} \) and \( 110.1 \mathrm{mg} / \mathrm{L} \) respectively. Calculate the combined concentration of these compounds in equivalents per liter \( (e q / L) \)
