What is the molar mass of mg3(po4)2, a substance formerly used in medicine as an antacid?

First let us determine the molar masses of each element.

Mg = 24.31 g/mol

P = 39.10 g/mol

O = 16 g/mol

Therefore the overall molar mass is:

molar mass = 3 * (24.31 g/mol) + 2 (39.10 g/mol) + 8 (16 g/mol)

molar mass = 279.13 g/mol

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.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
