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.

Wind turbines generate electricity by following a simple principle. Moving wind transfers energy to the blades of the windmill, which results in spinning of the blades. These blades are connected to an internal shaft which also starts spinning. This spinning of the shaft generates electricity, which is further distributed to electrical substations to provide electricity to homes and businesses.
<h3>What is a wind turbine?</h3>
Wind turbines work by creating kinetic energy when the power of the wind makes their blades spin. This kinetic energy is converted into electrical energy.
Thus, the steps describing how a wind turbine functions are,
Step 1: Wind moves the blades of the turbine.
Step 2: Internal shaft spins
Step 3: Generator produces electricity
Step 4: Distribution lines carry electricity to substation
