What is the formula weight of mercury (I) chloride?Question 3Select one:a.200.6b.236.0c.271.6d.472.2e.307.1

The formula weight of a compound can be calculated by adding up the atomic weights of each element in the compound, multiplied by the number of atoms of that element in the compound.

The formula for mercury (I) chloride is Hg2Cl2.

1. First, find the atomic weights of mercury (Hg) and chlorine (Cl). The atomic weight of mercury is approximately 200.59 amu and the atomic weight of chlorine is approximately 35.45 amu.

2. Multiply the atomic weight of mercury by the number of mercury atoms in the compound. In this case, there are 2 mercury atoms, so 200.59 amu * 2 = 401.18 amu.

3. Multiply the atomic weight of chlorine by the number of chlorine atoms in the compound. In this case, there are 2 chlorine atoms, so 35.45 amu * 2 = 70.9 amu.

4. Add the total atomic weights of mercury and chlorine together to find the formula weight of mercury (I) chloride. 401.18 amu + 70.9 amu = 472.08 amu.

So, the formula weight of mercury (I) chloride is approximately 472.08 amu, which is closest to 472.2 in your options. Therefore, the answer is d. 472.2.
