Question

what is the mass in grams of KBr in 0.400 L of a 0.350 M solution???

Answer 1

Okay, so first you want to know the moles in the KBr solution
- They told you this is a 0.350 M solution

\(.400\color{red}{\cancel{L}}\times\dfrac{0.350M}{\color{red}{1\cancel{L}}}=\)

From then you need to multiply what you get from above by the molar mass (Which is 119.002)

\(Moles\times Molar~mass \rightarrow Moles \times 119.002=\)

Answer 2

I got 16. 7 as my answer. Would that be right?

Answer 3

Yes

16.7 grams (rounded)

Answer 4

okay thank you
