Sodium Bromide, often used to kill algae in pools contains 77.65%
Br. Calculate the mass of sodium bromide in grams if a bottle sold
at the pool store contains 194.13 grams of bromide.
thank you for your help!
Homework Answers
We know that in general, the Br in NaBr is 77.65% of content. So if we have a bottle with 194.13 g of Br, this means that this mass is the 77.63%, so we can assume that the whole NaBr should weight more than that.
To calculate this, we just do calculations with %:
mass NaBr = 194.13 g Br * 100 g NaBr / 77.65 g Br
mass NaBr = 250.01 g
The last option is the correct one. Hope this helps

Question
A 20.0 mL sample solution contains unknown amount of bromide ion (Br). To this solution was added the solution that contains plenty of AgNO3. AgBr precipitates were formed. The precipitate were filtered and measured to be is 0.6964 g. What is the molarity of bromide ion in the original sample solution? The molar mass of Br = 80.0 g; the molar mass of AgBr = 188 g. (Solution) AgNO, is soluble and thus exists Ag+ ion and NO3-ion. Ag+...
