Explanation:
Answer:5/6
Explanation:
Each Coin has two possible outcomes heads or tails
if there are 3 coins and two outcomes for each coin you multiply 3 and 2 and that is a total of 6 possible outcomes
Since the question is saying it can't have more than 2 heads we subtract what we don't want with the total possible outcomes
Out of the 6 outcomes how many are there where all of the coins land on heads? Only 1
6-1=5
Out of 6 outcomes 5 of them the coins landed on 2 heads or less
5/6
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.
