#### Answer:

0.702 Molar for NaCl

#### Explanation:

The definition of Molarity is the number of moles per liter of solution. In that case you need to know the identity of the salt to give an answer. The most common salt is NaCl, so we can make that supposition.

$m o l = m / M {W}_{\text{NaCl}} = 155 g / \left(58.44 g / m o l\right) = 2.652 m o l$

Molarity = $m o l / V = 2.652 m o l / 3.78 L = 0.702 M$
