To convert grams to moles, we need the molar mass of the element or compound. remember you can determine the molar mass of a molecule by adding the atomic mass of each atom from the periodic table.
molar mass of Na= 23.0 g/ mol
130 g (1 mol Na/ 23.0 grams)= 5.65 moles or 6 moles.

Explanation:
This is the Difference Between a Hypothesis and a Theory. In scientific reasoning, a hypothesis is an assumption made before any research has been completed for the sake of testing. A theory on the other hand is a principle set to explain phenomena already supported by data.
Yes<u>, </u>Molybdenum(II) Bromide is a high water-soluble and lead nitrate
<u>Explanation:</u>
- Molybdenum(II) Bromide is a high water-soluble, crystalline form of molybdenum for use consistent with bromides and lower (acid) pH.
- Metallic bromides are traded under the trade name AE Bromides™.
- For some applications of crystal production, most metal bromide compounds remain water-soluble as used in water treatment, chemical division, and ultra-high purity.
- Bromide can be measured using the addition of carbon disulfide (CS2) and chlorine in an aqueous solution.
