Answer: 0.335 moles
Explanation:
Given that,
Amount of moles of KBr solute (n) = ?
Volume of KBr solution (v) = 0.67 L
Concentration of KBr solution (c) = 0.50M
Since concentration (c) is obtained by dividing the amount of solute dissolved by the volume of solvent, hence
c = n / v
make n the subject formula
n = c x v
n = 0.50M x 0.67L
n = 0.335 moles
Thus, there are 0.335 moles of KBr in 0.67 L of a 0.50 M KBr solution

Answer:
The answer is True.
Explanation:
You can use similar processes when converting from smaller to larger units. When converting a larger unit to a smaller one, you multiply; when you convert a smaller unit to a larger one, you divide.
