In determining a concentration, we need to convert the result into Grams / Liter

We already have the correct conversion of the weight , now we just need to convert the water volume into Liter :

185.8 / 1000 = 0.1858 L

The concentration is :
weight / volume

= 13.7 gram / 0.1858 L
= 73.73 gram/liter
