There are ________ mol of bromide ions in 0.500 L of a 0.350 M solution of AlBr₃. A)0.150 B)0.0500 C)0.525 D)0.167 E)0.500

Question

Quizplus · Accepted Answer

To determine the number of moles of bromide ions in the solution, we first need to determine the number of moles of aluminum bromide in the solution using the given concentration and volume:

moles of AlBr3 = concentration x volume
moles of AlBr3 = 0.350 M x 0.500 L
moles of AlBr3 = 0.175 mol

Since aluminum bromide dissociates into three ions in solution (Al3+, 3Br-), the number of moles of bromide ions will be three times the number of moles of aluminum bromide:

moles of Br- = 3 x moles of AlBr3
moles of Br- = 3 x 0.175 mol
moles of Br- = 0.525 mol

Therefore, there are 0.525 mol of bromide ions in 0.500 L of the solution, which corresponds to answer choice C.
