What about? You must provide a question :)
Answer:
a) 6.3 cm
b) 8.0 cm
c) 0.7875
Explanation:
(a) The compound has moved above upto 7.3 cm from the bottom of the paper. Let us assume that line is drawn at 1.0 cm mark as the origin of spot. \
Distance traversed by compound= 7.3 - 1.0 cm = 6.3 cm
(b) Distance traversed by the solvent = 9.0 - 1.0 cm = 8.0 cm
(c) The Rf = Compound Migration distance / Solvent front migration distance
= 6.3/8.0 = 0.7875
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
Answer:
The 3 rd answer
Explanation:
Atomic number is the number of protons in the nucleus of that element...
Mass number is the the sum of protons and neutrons in the nucleus of the atom..
