Answer:
0.85 mol/L.
Explanation:
- Molarity is defined as the no. of moles of solute dissolved in a liter of the solution.
<em>M = (no. of moles of solute)/(Volume of the solution (L))</em>
no. of moles of calcium phosphate = 2.125 mol.
Volume of the solution = 2.5 L.
<em>∴ M of calcium phosphate</em> = (2.125 mol)/(2.5 L) = <em>0.85 mol/L.</em>
Umm what is your question
Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction. When oxidation occurs, the oxidation state of the chemical species increases. Oxidation doesn't necessarily involve oxygen!
Answer:
0.0478 L
Explanation:
Given data
- Initial volume (V₁): 1.91 L
- Initial pressure (P₁): 1.00 atm
- Final pressure (P₂): 40.0 atm
We can find the final volume of an ideal gas using Boyle´s law.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁ / P₂
V₂ = 1.00 atm × 1.91 L / 40.0 atm
V₂ = 0.0478 L
The final volume is 0.0478 L = 47.8 mL.
