Calculate the mass of forsterite Mg2SiO4 that contains a million ×1.00106 oxygen atoms. Be sure your answer has a unit symbol if necessary, and round it to 3 significant digits.

5.84x10⁻¹⁷ g

Explanation:

First we convert oxygen atoms into oxygen moles, using Avogadro's number:

Now we convert oxygen moles into forsterite moles, using forsterite's molecular formula:

Finally we convert forsterite moles into grams using its molecular weight:

c is the answer because when something is left after something evaporates that shows the chemical change.

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
