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.

Musculoskeletal Health can be efficiently maintained by proper nutrition and regular physical exercise programs.
<h3>What does musculoskeletal health mean?</h3>
The expression 'musculoskeletal health' makes reference to the activities aimed at preserving the health of the muscles and skeletal system.
The muscles that are attached to the skeletal system are called skeletal muscles, and they can be maintained by proper nutrition (consuming proteins) and physical exercise.
Moreover, the bones of the skeletal system need calcium to maintain their strength and rigid structure.
In conclusion, musculoskeletal health can be efficiently maintained by proper nutrition and regular physical exercise programs.

Using the accrual method, the unearned revenue as of December 31 is $12,000.
<h3>What is Unearned revenue?</h3>
Unearned revenue can be defined as the amount a company received from their client for the service they are yet too rendered.
Since the company has received full balance for the services not yet provided. The unearned revenue as of December 31 will be $12,000.
Reason been that the amount that the client paid the company is for a year-long contract, hence the $12,000 represent a prepayment amount for the service the company is yet too rendered to their client
Thus, using the accrual method, the unearned revenue as of December 31 is $12,000.
