Question

We can use the formula:
moles = concentration x volume (in liters)

Firstly, we need to convert mL to liters:
55.0 mL = 0.0550 L

Then, we can plug in the values we know and solve for moles:
moles = 1.90 M x 0.0550 L = 0.1045 moles

Finally, we can use the molar mass of sodium chloride (58.44 g/mol) to convert moles to grams:
grams = 0.1045 moles x 58.44 g/mol = 6.11 g

Therefore, the answer is B: 6.11.
