Answer:
0.0102 mole
Explanation:
Use and solve proportions for these with x as the unknown value.
I think it’s c I could be wrong
Molecular formula=C3H6
Explanation
As with all of these problems, we assume 100 * g of unknown compound. And this, we determine the elemental composition by the given percentages.
Miles of carbon= 85.64*g/12.011*g*mol-1=14.25*mol
Clearly there are 3 mols of hydrogen per mol of carbon. And thus the empirical formula is CH2.
And molecular formula=n*(12.011+2*1.00794)*g*mol-1
And this n=3, and molecular formula=C3H6.
Answer:
0.220 M
Explanation:
<em>In the equivalence point, [H⁺] = [OH⁻]</em>.
This means we can use the formula C₁V₁=C₂V₂
Where
So we <u>compute the given data in the formula</u> to calculate C₂:
- 0.0500 M * 17.6 mL = C₂ * 4.00 mL
