The basic difference between thin layer chromatography (TLC) and paper chromatography (PC) is that, while the stationary phase in PC is paper, the stationary phase in TLC is a thin layer of an inert substance supported on a flat, unreactive surface. ... Paper chromatography is performed using paper.
Answer:
957.7mL
Explanation:
Using the formula below;
CaVa = CbVb
Where;
Ca = concentration of acid (M)
Va = volume of acid (mL)
Cb = concentration of base (M)
Vb = volume of base (mL)
According to the information provided in this question:
Ca = 0.166 M
Cb = 0.013 M
Va = 75mL
Vb = ?
Using CaVa = CbVb
0.166 × 75 = 0.013 × Vb
12.45 = 0.013Vb
Vb =12.45/0.013
Vb = 957.7mL
Answer:
<h2>3.31 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 23.2 g
volume = final volume of water - initial volume of water
volume = 62 - 55 = 7 mL
We have
We have the final answer as
<h3>3.31 g/mL</h3>
