<span>If a 2L bottle contains 27% juice, then the bottle contains about 0.54L of juice.
I assumed that, since most bottles contain 27% juice, that this would be no different.
27% of 2.00L, is 0.54L.</span>
24.063/8.021 = 3 half lives
(1/2)^3 =1/8
Answer:
2.77 mL of boiling water is the minimum amount which will dissolve 500 mg of phthalic acid.
Explanation:
We know from the problem that 18 g of phthalic acid are dissolved in 100 mL of water at 99 °C.
Now we devise the following reasoning:
If 18 g of phthalic acid are dissolved in 100 mL of water at 99 °C
Then 0.5 g of phthalic acid are dissolved in X mL of water at 99 °C
X = (0.5 × 100) / 18 = 2.77 mL of water
