Answer 1

Hey!

First convert grams of NaCl to moles of NaCl.

From the periodic table:

Na = 23.0 g/mol

Cl = 35.5 g/mol

NaCl = 23.0 g/mol + 35.5 g/mol = 58.5 g/mol

Total number of moles = (1 mole / 58.5 g) * 6 g = 0.62 moles

Now determine moles per liter of solution:

M = 0.62 moles NaCl / 0.50 liter solution = 1.2 M solution (1.2 molar solution)
