The average atomic mass of element X is 10.025 amu
The average atomic mass of element X = atomic mass of 10 isotope × relative abundance of 10 isotope + atomic mass of 11 isotope × relative abundance of 11 isotope + atomic mass of 12 isotope × relative abundance of 12 isotope
= 10 × 98% + 11 × 1.5 % + 12 × 0.5 %
= 10 × 0.98 + 11 × 0.015 + 12 × 0.005
= 9.8 + 0.165 + 0.06
= 10.025 amu
So, the average atomic mass of element X is 10.025 amu

The solution that will have the lowest freezing point is 5.0 SODIUM CHLORIDE.
Adding solute to solvents usually result in the depression of the freezing point. The higher the quantity of the solute that is added, the lower the freezing point of the solution.
Answer: ![Rate=k[O_3][NO_2]^2](https://tex.z-dn.net/?f=Rate%3Dk%5BO_3%5D%5BNO_2%5D%5E2)
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
slow
fast
To determine the net chemical equation, we will simply add the above two equations, we get:
Order with respect to 
is 1 and Order with respect to 
is 2.
Thus the rate law will be:
