In an aldehyde, the carbonyl is at the end of a carbon chain, while in a ketone, it is in the middle. A carboxylic acid contains the carboxyl functional group. They are weak acids because the hydrogen of the hydroxyl group is ionizable. In an ester, the hydrogen of a carboxylic acid group is replaced by an alkyl group.

If the volume of a solution is 25.6 L and its molarity is 8.20 M, how many moles of solute are
harkovskaia [24]

Answer:

210 moles

Explanation:

From the question given above, the following data were obtained:

Volume of solution = 25.6 L

Molarity = 8.20 M

Mole of solute =?

Molarity is simply defined as the mole of solute per unit litre of water. Mathematically, it can be expressed as:

Molarity = mole /Volume

With the above formula, the mole of solute dissolved can be obtained as follow:

Volume of solution = 25.6 L

Molarity = 8.20 M

Mole of solute =?

Molarity = mole /Volume

8.20 = mole / 25.6

Cross multiply

Mole = 8.20 × 25.6

Mole = 209.92 ≈ 210 moles

Thus, the mole of solute dissolved in the solution is 210 moles

which equation is set up correctly to determine the volume of a 1.5 mole sample of oxygen gas at 22 C and 100kPa
Murljashka [212]
Under STP condition, the gas has a rule of 22.4 L per mole. And according to the ideal gas law, V1/T1=V2/T2. Under STP, 1.5 mol gas has volume of 33.6 L. So the volume under 22 C is 33.6*295/273=36.3 L.
