Answer:
8.13 ×10²³ atoms
Explanation:
Given data:
Mass of magnesium = 32.45 g
Number of atoms = ?
Solution:
Number of moles of Mg:
Number of moles = mass/molar mass
Number of moles = 32.45 g/ 24 g/mol
Number of moles = 1.35 mol
Number of atoms:
1 mole contain 6.022×10²³ atoms
1.35 mol × 6.022×10²³ atoms/ 1mol
8.13 ×10²³ atoms
I think it would be solubility but I’m not sure
Answer: The number of protons

Answer:
A. Chemical Reaction
Explanation:
Cellular Respiration is the chemical reaction in which glucose and oxygen are turned into water, carbon dioxide, and energy.
69 mmHg pressure is exerted by oxygen if 40% of the gas pressure is exerted by the oxygen gas.
<h3>What is pressure?</h3>
Pressure is defined to be the amount of force exerted per area
40% of pressure is exerted by oxygen gas.
So, 60% of pressure will be exerted by carbon dioxide gas.
60% of 115 mmHg = 69 mmHg
Hence, 69 mmHg pressure is exerted by oxygen if 40% of the gas pressure is exerted by the oxygen gas.
