In a laboratory setting, concentrations for solutions are measured in molarity, which is the number of moles per liter (mol/L). Concentrations are often converted to more common units on the labels of household products. For a particular brand of bleach, the concentration of sodium hypochlorite (NaClO) is reported on the bottle as 7.25% by mass. The following information can thus be used to calculate the molarity of NaClO in the bleach: • 1L of bleach has a mass of 1,100 grams.

• 7.25% of the mass of bleach is NaClO.

• 1 mol of NaClO has a mass of 74.44 grams.

What is the molarity (mol/L) of NaClO in the bleach?

A.0.097
B.0.93
C.1.07
D.79.75
