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:
The author makes this claim in the passage: Keeping animals in zoos is cruel and unfair to the animals.
The author supports this claim by discussing three major problems with zoos. The first problem is that zoos cause behavior problems in animals. The author supports this claim by mentioning studies that prove the claim. The author also states that zoos do not consider the specific traits of different animals. The author cites a study of a zoo in Belfast, Ireland, to support this claim. Lastly, the author states that zoos do not focus on protecting endangered animals. The author supports this claim by noting the number of zoos worldwide that support wildlife conservation.
