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.

The price elasticities of demand of sugar-free gummy bears and of ordinary gummy bears is -0.8 and -2.3 respectively.
<h3>How to calculate price elasticity</h3>
Change in price of gummy bears = $2. 60 to $3
Elasticity of demand of sugar-free gummy bears =
[(273-379 / (273+379)/2] ÷ [(3.00-2.60)/(3.00+2.60) / 2]
= [-18/166] / [0.4/2.8]
= -0.10843373493975 / 0.14285714285714
= - 0.75903614457826
Approximately, -0.8
Elasticity of demand of regular gummy bears:
Sugar free = [(273-379) / (273+379)/2] ÷ (3.00 +2.60) / 2]
= [-106/326] / [0.4/2.8]
= -0.32515337423312 / 0.14285714285714
= -2.2760736196318
Approximately, -2.3
