Find a mole of 0.0960 g of H2SO4

nignag [31]

Molar mass H₂SO₄ = 98.079 g/mol

1 mol -------- 98.079 g
? mole ------ 0.0960 g

moles = 0.0960 * 1 / 98.079

= 0.0960 / 98.079

= 9.788 x 10⁻⁴ moles

hope this helps!

What is the average atomic mass of the element?

morpeh [17]

The average atomic mass of element X is 14.007 u.

The average atomic mass of X is the <em>weighted average</em> of the atomic masses of its isotopes.

We multiply the atomic mass of each isotope by a number representing its <em>relative importance</em> (i.e., its % abundance).

Thus,

0.996 36 × 14.003 u =13.952 03 u

0.003 64 × 15.000 u = <u>0.054 60 u</u>

__________TOTAL = 14.007 u

Aspirin (C9H8O4) may be synthesized by mixing salicylic acid (C7H6O3) with excess acetic anhydride (C4H6O3).

diamong [38]

Answer:

65.18% is the percent yield for this reaction.

Explanation:

$C_7H_6O_3 + C_4H_6O_3\rightarrow C_9H_8O_4 + C_2H_4O_2$

Moles of salicyclic acid = $\frac{2.0 g}{138 g/mol}=0.01449 mol$

According to reaction 1 mole of salicyclic acid gives 1 mole of aspirin .

Then 0.01449 mole of salicylic acid will give :

$\frac{1}{1}\times 0.01449 mol=0.01449 mol$ of asprin

Mass of 0.01449 moles of aspirin :

= 0.01449 mol × 180 g/mol = 2.6082 g

Theoretical yield of aspirin = 2.6082 g

Experimental yield of aspirin = 1.7 g

The percent yield for this reaction:

$\%(Yield)=\frac{\text{Experimental yield}}{\text{Theoretical yield}}\times 100$

$=\frac{1.7 g}{2.6082 g}\times 100=65.18\%$

65.18% is the percent yield for this reaction.
