The chemical reaction is the oxidation of calcium metal by molecular oxygen. During the reaction, calcium metal is oxidized, that is, loses electrons and oxygen is reduced, that is gains electrons.
During the reaction, the calcium atom donate two electrons in order to become stable and the oxygen atom accepts these two electrons. Therefore, during the reaction, EACH OXYGEN ATOM GAINS TWO ELECTRONS.
The osmotic pressure of the 0.250 L solution made with 1.60 g of glucose, in water at 25.00°C is 0.869atm.
<h3>How to calculate osmotic pressure?</h3>
The osmotic pressure of the solution can be calculated using the following expression:
PV = nRT
where;
- P = pressure
- V = volume
- n = no of moles
- T = temperature
- R = gas law constant
no of moles of glucose = 1.60g ÷ 180g/mol = 8.89 × 10-³mol
P × 0.250 = 0.00889 × 0.08206 × 298
0.25P = 0.217
P = 0.217/0.25
P = 0.869atm
Therefore, the osmotic pressure of the 0.250 L solution made with 1.60 g of glucose, in water at 25.00°C is 0.869atm.
