Question

you have 17.0g of bleach solution The percent by mass of the solute sodium hypochlorite is 13.9% how many grams of solution do you have?

Answer 1

Answer:

2.36 g of solute

Explanation:

Note: I assume that the problem is asking to find the grams of solute, since the grams of solution are already given (17.0g).

A solution consists of two substances: a solute and a solvent. In particular:

• The solute is the substance that is dissolved in the solvent (generally, the solute is in solid form)
• The solvent is the substance making the majority of the solution, and in which the solute is dissolved (generally, the solvent is in liquid form)

In this problem, we know that the total mass of the solution (solute + solvent) is

$m=17.0 g$

And we know that the percentage of solute in the solution is

$p=13.9\%$

Therefore, the mass of the solute can be written as

$m_s = \frac{13.9}{100}m$

And substituting the mass of the solution, we find:

$m_s = \frac{13.9}{100}(17.0)=2.36 g$
