The mass of the acetic acid is 1.512 g.
<h3 /><h3>What is Molarity?</h3>
molarity is the concentration of a substance in mol per dm³
From the question,
The number of moles contained in the 30 mL vinegar is
- n = (0.84×30)/1000
- n = 0.0252 mol.
the molar mass of vinegar is calculated below.
- m.m of (HC₂H₃O₂) = [1+(12×2)+(1×3)+(16×2)]
- m.m = (1+24+3+32]
- m.m = 60 g/mol.
To calculate the mass of acetic acid, we use the formula below.
- R.m = n×m.m............. Equation 1
Where
- R.m = mass of acetic acid.
Substitute these values into equation 1
- R.m = (0.0252×60)
- R.m = 1.512 g.
Hence, The mass of the acetic acid is 1.512 g.

This is so hard to answer.
One thing that aldosterone is able to affect from the given options is A) regulation of body fluid concentration along the distal convoluted tubule and collecting duct.
<h3 /><h3>What does aldosterone do?</h3>
The aldosterone hormone has several functions in the body due to its nature as a steroid hormone. One thing that is does is to control the balance of water in the kidney.
To be more technical, it regulates the body fluid concentration along the distal convoluted tubule and collecting duct by keeping the level of water and sale balanced. It does this by controlling sodium and potassium levels.
Options for this question include:
- A) regulation of body fluid concentration along the distal convoluted tubule and collecting duct
- B) osmotic flow of water in the proximal convoluted tubule
- C) removal of wastes through the entire renal tubule
- D) pH regulation
- E) formation of plasma proteins
