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.

Answer:
(x-4)(x-12)
Explanation:
+
Break the expression into groups
Factor out x from x^2 - 4x : 
Factor out -12 from -12x + 48: 
= x(x-4)-12(x-4)
Factor out common term x-4
= (x-4)(x-12)
Since in Croatia, there is only one company that provides all of the telephone services for the entire country, this is called a monopoly.
<h3>What is a monopoly?</h3>
