**QUESTION:**

Calculate the concentration of each solution in mass percent.

(a) 41.2 g \(\mathrm {C_{12}H_{22}O_{11}}\) in 498 g \(\mathrm {H_2O}\)

(b) 178 mg \(\mathrm {C_6H_{12}O_6}\) in 4.91 g \(\mathrm {H_2O}\)

(c) 7.55 g NaCl in 155 g \(\mathrm {H_2O}\)

**ANSWER:**

Step 1 of 4

The given information are:

a. \(41.2\;{\rm{g}}\;{C_{12}}{H_{22}}{O_{11}}\) in \(498\;{\rm{g}}\;{H_2}O\)

b. \(178\;{\rm{mg}}\;{C_6}{H_{12}}{O_6}\) in \(4.91\;{\rm{g}}\;{H_2}O\)

c. \(7.55\;{\rm{g}}\;NaCl\) in \(155\;{\rm{g}}\;{H_2}O\)
