Carbonated cola is more acidic than coffee or even orange juice because cola contains phosphoric acid. what is the molar concentration of [h3o+] in a cola that has a ph of 3.120? (for with significant figures, see hint 3.) view available hint(s) what is the molar concentration of [h3o+] in a cola that has a ph of 3.120? (for with significant figures, see hint 3.) 7.58 × 10−4 7.59 × 10−4 7.6 × 10−4 3.120 × 10−3 0.494 1.318 × 103

Answer;

= 7.59 × 10^-4 M

Explanation;

The molar concentration of [H3O+] in a cola with a pH of 3.120 can be calculated by:

[H3O+]=10−pH

[H3O+]=10−3.120

[H3O+]=7.59×10−4M

Ingestion of large amounts of phosphoric acid found in cola can upset the body's regulation of bone metabolism and reduce the absorption of calcium from the diet. For this reason, people who are at risk of developing osteoporosis are often advised not to drink much cola.

girl imma just put my comment here because i need a couple point okurrttt
