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 first one is D the second one is false.
Answer: 0.99
Explanation:
Chance she will use red roses: 98%
Chance she will use orchids: 87%
Chance she will use Gerber daisies: 94%
probability she has both roses and orchids: 0.82
Probability she has both Gerber daisies and roses: 0.97
What is the probability she has Gerber daisies as she has already chosen red roses =?
Probability of having daisies and choosing red roses= Probability of Daisies and roses/ Probability of red roses)
0.97/0.98 = 0.99
