What is the simplest method of determining the composition of a compound?
kaheart [24]

Answer:

Chemical formulas tell you how many atoms of each element are in a compound, and <u>empirical formulas</u> tell you the simplest or most reduced ratio of elements in a compound. If a compound's chemical formula cannot be reduced anymore, then the empirical formula is the same as the chemical formula.

g If the titration of a 10.0-mL sample of sulfuric acid requires 28.15 mL of 0.100 M sodium hydroxide, what is the molarity of t
Leona [35]

Answer:

M_{acid}=0.141M

Explanation:

Hello,

In this case, the reaction between sulfuric acid and hydroxide is:

H_2SO_4+2NaOH\rightarrow Na_2SO_4+2H_2O

We can notice a 1:2 molar ratio between the acid and the base respectively, therefore, at the equivalence point we have:

2*n_{acid}=n_{base}

And in terms of volumes and concentrations:

2*M_{acid}V_{acid}=M_{base}V_{base}

So we compute the molarity of sulfuric acid as shown below:

M_{acid}=\frac{M_{base}V_{base}}{2*V_{acid}} =\frac{0.100M*28.15mL}{2*10.0mL}\\ \\M_{acid}=0.141M

Best regards.
