Answer: 1.09 g
Explanation:
If we use the approximation that 1 mole is 22.4 L, then setting up a proportion,
- 1/22.4 = x/0.345 (x is the number of moles in the sample)
- x = 0.0154 mol
Since the mass of a mole of chlroine is about 70.9 g/mol, (0.0154)(70.9) = 1.09 g (to 3 s.f.)
Answer:
Density measures the amount of mass per unit of volume in a substance. Concentration describes the amount of a substance dissolved in another substance. Changing the concentration of a solution changes the density of the solution.
Answer:
the answer is 2.75 but since that isn't an option I'd go with 1 because I just took a test with this question and it was the right answer.. hopefully that helps
Answer:
[Y₂] = 31.25M
Explanation:
Based on the chemical reaction:
2X(g) + Y2(g) ⇌ 2XY(s)
We must define the equilibrium constant, K as:
K = 20 = 1 / [X]²[Y₂]
<em>Where</em> [X] and [Y₂]<em> are the equilibrium concentrations of each gas.</em>
<em />
If [X] = 4.0x10⁻²M:
20 = 1 / [4.0x10⁻²M]²[Y₂]
0.032 = 1 / [Y₂]
<h3>[Y₂] = 31.25M</h3>
One compound can be differentiate from other by its composition although both look same. The diamond has the chemical formula of carbon (c) as it is a repeating unit of carbon which has shining features. On the other hand zirconia is zirconium dioxide (Zr. When it is crystallized it becomes shiny as like diamond. However the look of the two are meanwhile similar the composition is totally different as well the molar mass.
