Explanation:
B----------- oxide is the correct answer
-they are inside the nucleus of an atom
- they have a relative charge of +1
- they have a relative mass of 1
The molarity of a solution equals to the mole number of the solute/the volume of the solution. For NH4Br, we know that the mole mass is 98. So the molarity is (14/98) mol /0.15 L=0.95 mol/L.
