Assuming we have 100g, this means that
39.97g Carbon * 1 mol / 12 g = 3.33 mol Carbon
13.41g Hydrogen * 1 mol/1 g = 13.41 mol Hydrogen
46.62g Nitrogen * 1 mol / 14 g = 3.33 mol Nitrogen
Dividing everything by 3.33, we get
1 mol Carbon, 4.03 mol Hydrogen, 1 mol Nitrogen.
Empirical formula is CH4N
<span>The mass of the empirical formula is
12 + 4 + 14 = 30
Since the molar mass is double, we multiply all our subscripts
The molecular formula is C2H8N2
The answers to this question are </span><span>an empirical formula of CH4N</span> and a molecular formula of C2H8N2 .
Answer:
[KI] = 0.17 M
Explanation:
We determine the moles of solute:
Mass / Molar mass → 4.73 g / 166 g/mol = 0.0285 moles
Molarity (mol/L) is defined as moles of solute in 1L of solution
It is a sort of concentration
M = 0.0285 mol / 0.169L = 0.17 M
Instead of making the division (mol/L), we can also try this rule of three:
In 0.169 L we have 0.0285 moles of solute
in 1 L we must have ___ (1 . 0.0285) / 0.169 = 0.17 mol/L
I dont understand life, for example, look at my username.
Answer:
Normal cells are either repaired or die (undergo apoptosis) when they are damaged or get old. Cancer cells are either not repaired or do not undergo apoptosis.
