Answer:
The density will be 1.48 g/ mL.
Explanation:
The answer is D, alters the test variable, and observes the effects on other outcome variables.
The molar mass of the unknown compound is <u>223.2 g/mol.</u>
<u />
Solution:
Molarity =
Molecular weight =<u> 223.2 g/mol</u>
<u />
The main difference between the two is that molar mass refers to the mass of one mole of a particular substance. Molecular weight is the mass of a molecule of a particular substance. Although the definitions and units of molar mass and molecular weight are different, the values are the same.
The formula mass of a molecule is the sum of the atomic weights of the atoms in that molecular formula. The molecular weight of a molecule is the average mass calculated by adding the atomic weights of the atoms in the molecular formula. Molecular weight is the mass of a single molecule, specifically the mass of material required to make a single mole.

I can tell you about:
- What natura transmutation is
- Which elements suffer natural transmutation
- Some examples of nuclear equation representing natural transmutation
1) Natural transmutation is the transmutation that occurs in nature without intervention of human beings. So, the natural transmutation is the natural decay of elements into other (smaller) elements. The transmutation of the elements consists in the emission of particles (alpha emission, beta emission, positron emission or electron emission) and the obtention of a smaller element.
2) Which elements undergo natural transmutation.
The heavier elements, after lead, are radioactive and so they decay into lighter (smaller) elements. Those elements are unstable due to the relation proton / neutron.
3) Transmutation equation examples
I131 ----> Xe131 + Beta particle
Ra222 ---> Rn218 + 2He4 (same alpha particle)
90Th234 ----> 89Pa234 + beta particle
92U238 ----> 90Th 234 + 2He4 (same alpha particle)
