Answer:
The answer to the question is;
The concentration of the Solution #1 in terms of molarity is
0.16704X moles/litre.
Explanation:
Let the concentration of the stock solution be X moles/liter
Therefore, 83.52 ml of the stock solution contains
83.52×(X/1000) moles
Dilution of 83.52 ml of X to 500 ml gives solution 1 with a concentration of
500 ml of solution 1 contains 83.52×(X/1000) moles
Therefore 1000 ml or 1 litre contains 2×83.52×(X/1000) moles = 0.16704X moles/litre
The molarity of solution 1 is 0.16704X moles/litre.
Answer:
Carbon fiber if I'm correct
You add solute until it can't dissolve anymore.
Answer:
A. 35Cl1-
Explanation:
Chlorine needs 1 more electron to have full octet thus will take 1 electron and possess a -1 charge.
Answer:
24.68 g/cm³
Explanation:
We'll begin by calculating the volume of the marble. This can be obtained as follow:
Volume = 17 × 23 × 4
Volume = 1564 cm³
Next, we shall convert the mass of the marble (i.e 38.6 kg) to grams (g). This can be obtained as follow:
1 kg = 1000 g
Therefore,
38.6 kg = 38.6 kg × 1000 g / 1 kg
38.6 kg = 38600 g
Therefore, 38.6 kg mass of the marble slab is equivalent to 38600 g.
Finally, we shall determine the density of the marble slab as follow:
Volume = 1564 cm³
Mass = 38600 g.
Density =..?
Density = mass /volume
Density = 38600 g / 1564 cm³
Density = 24.68 g/cm³
Therefore, the density of the marble slab is 24.68 g/cm³
