Question

What volume (in L) of 1.40 M FeBr₂ would be required to obtain 0.500 moles of Br⁻ ions?

Answer 1

The volume, in Liters, that would be required to obtain 0.500 moles of Br ions from 1.40 M FeBr2 will be 0.36 L

Stoichiometric calculation

Recall that:

Molarity = mole/volume

In this case, molarity = 1.40 M and moles = 0.500 moles

Thus:

Volume = mole/molarity = 0.500/1.40 = 0.36 L
