What volume of 0.716 M KBr solution is needed to provide 10.5 g of KBr?
Added by Kayla L.
Step 1
5 g. We can do this using the molar mass of KBr, which is 39.1 g/mol (for K) + 79.9 g/mol (for Br) = 119 g/mol. Moles of KBr = (10.5 g) / (119 g/mol) = 0.088235 moles Now, we can use the molarity of the KBr solution to find the volume needed. Molarity is defined Show more…
