Answer: The empirical formula will be
Explanation:
If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of S= 3.21 g
Mass of F = 11.4 g
Step 1 : convert given masses into moles.
Moles of S =
Moles of F =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For S=
For F =
The ratio of S: F= 1: 6
Hence the empirical formula is
<u>Answer:</u> The volume of isopropyl alcohol present is 254.4 mL and the volume of water present is 540.6 mL
<u>Explanation:</u>
We are given:
32.0 % (v/v) alcohol solution
This means that 32 mL of isopropyl alcohol is present in 100 mL of solution
Volume of water = 100 - 32 = 68 mL
Volume of solution given = 795 mL
Applying unitary method:
In 100 mL of solution, the volume of isopropyl alcohol present is 32 mL
So, in 795 mL of solution, the volume of isopropyl alcohol present will be =
Volume of water in given amount of solution = 795 - 254.4 = 540.6 mL
Hence, the volume of isopropyl alcohol present is 254.4 mL and the volume of water present is 540.6 mL
