Answer:

1.7 M

Explanation:

Concentration is the number of moles of solute dissolved in 1 L of solution

Concentration = number of moles of solute / volume of solution

Number of moles of solute needs to be calculated first

Mass of methanol - 12.5 g

Molar mass of methanol - 32 g/mol

Number of methanol moles - 12.5 g / 32 g/mol = 0.39 mol

Therefore concentration is = 0.39 mol / 0.230 L = 1.7 mol/L

Concentration is 1.7 M

<span>If 36 gm of potassium chlorate enter into the reaction, the total mass of the two products will still be 36 gm because if there is only one reactant, the mass of the compounds after the reaction will be same that reactant based on the law of conservation of matter.</span>

The mechanism for producing a concentrated urine involves all of the following except
avanturin [10]

Answer:

The correct answer is "obligatory water reabsorption in the proximal convoluted tubule".

Explanation:

The mechanism for producing concentrated urine cannot include the obligatory reabsorption of water in the proximal convoluted tubule since this process is part of the nephron, the system that filters the blood. Glucose and amino acids are reabsorbed almost entirely, as are approximately 70% of filtered potassium and 80% of bicarbonate.
