1. <em>Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period. </em>
<em>2. Physical state of the reactants and surface area.</em>
<span>moles water = 850.0 g / 18.02 g/mol=47.2
moles Mg2+ = 0.400
moles Cl- = 2 x 0.400 = 0.800
moles ions = 0.400 + 0.800= 1.2
mole fraction ions = 1.2 / 1.2 + 47.2 =0.0248</span>
