The answer is 28.02.
The chemical formula for cadmium nitrate is Cd(NO₃)₂.
There are in total 2 nitrogen atoms in Cd(NO₃)₂. If <span>the atomic weight of nitrogen is 14.01</span>, the mass <span>of two nitrogen atoms in one mole of cadmium nitrate is 28.02:
2 </span>· 14.01 = 28.02
The reactants are what is put into the reaction equation to get the product. In this case water and ammonia are put into the equation to get the product ammonium hydroxide.
The first choice is the correct answer:

Zinc is available in capsules, tablets, creams, ointments, and a liquid form. Adults aged 19 years and over who are interested in using zinc supplements should be careful to consume no more than 40 mg per day. Too much zinc can cause health problems.
Kinetic energy is proportional to the velocity squared, so increasing in velocity will have an exponentially greater affect on translational kinetic energy. if you doubled the mass of an object it will double only it’s kinetic energy, but doubling the velocity of the object will quadruple its velocity.
