1.) Write down the number of atoms that comprise each compound on either side of the equation. Using the chemical equation you can identify the atoms of each element in the reaction. Because a chemical reaction can never create or destroy new matter, a given equation is unbalanced if the number (and types) of atoms on each side of the equation don't perfectly match.Don’t forget to multiply through by a coefficient or subscript if one is present.

For example, H2SO4 + Fe ---> Fe2(SO4)3 + H2On the reactant (left) side of the equation there are 2 H, 1 S, 4 O, and 1 Fe.On the product (right) side of the equation there are 2H, 3 S, 12 O, and 2 Fe.

A solution contains 15 ppm of benzene. The density of the solution is 1.00 g/mL. This means that ________.
snow_tiger [21]

Answer:

  • second choice:<em><u> 1.0 g of the solution contains 15 × 10⁻⁶ g of benzene.</u></em>

Explanation:

ppm is a unit of concentration that means parts per million. In grams that is grams of solute per one million (10⁶) grams of solution.

Then, <em>15 ppm of benzene</em> means that there are 15 grams of benzen in 1,000,000 grams of solution.

That leads to:

  • 1,000,000 g solution / 15 g benzene

Multiplying numerator and denominator by 10⁻⁶ you find:

  • 1,000,000 × 10⁻⁶ g solution / (15 × 10⁻⁶ g benzene)

Simplifying:

  • 1.0 g solution / (15 × 10⁻⁶ g benzene)

Which is read as 1.0 g of the solution contains 15 × 10⁻⁶ g of benzene, i.e. the second answer choice.
