Question

Sodium alkylbenzene sulfonate(C18H29SO3Na) is often used as asynthetic detergent. This ingredient helps prevent scale buildup in"hard" water applications. If a detergent solution were0.138 M in sodium alkylbenzenesulfonate, how many grams would be dissolved per liter ofsolution?
_______________ g/L

_______________ g/L

Explanation / Answer

How many grams is that? Well, to convert moles to grams,you have to add up the total molecular weight of the detergentbased on its molecular formula. I came up with about 348g/mol (that's how much one mol of it would weigh based on theatomic weights of each element that makes it up).
Looking at units for your cue, you multiply 0.138 moles x 348grams/mole and that will give you the number of grams (per literbecause we're still pretending to only have one liter ofsolution).
For checking purposes, my final answer was about 48.0 gramsper liter.
