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.

Explanation:
I hope it helps Let me know.
The matchup statement associated with rods or cones are:
<h3>Rods:</h3>
- involved with night vision
- smooth plasma membrane surrounding the intramembranous discs
- uses rhodopsin
- used in scotopic vision
- absorption peak occurs at 500 nm
<h3>Cones:</h3>
- highly concentrated in and around the macula
- involved with color vision
- infolded plasma membrane surrounds each disc
- uses photopsin
- absorption peaks occur at 420, 531, and 558 nm
<h3>What are the roles of rods and cones in the eye?</h3>
The Rods are known to help in regards to vision at low light levels or scotopic vision.
The cones are known to help or function in regards to vision at the point of higher light levels or what we call photopic vision.
Hence the matchup above are correct.
