chemistry help. best answer= 10 points!?

First step is to convert it from molarity to moles and we can do that since we're given both the molarity and the volume.
1.50M NaCl * 6.00L = 9mol NaCl

Next, we determine the molar mass of NaCl (use the periodic table)
Na = 22.98977g/mol Cl = 35.453g/mol
NaCl = 22.98977g/mol + 35.453g/mol = 58.44277g/mol NaCl

Now, we just multiply the number of moles to the molar mass to determine the mass of NaCl.
58.4427g/mol NaCl * 9mol NaCl = 525.98493g NaCl

Remember to consider significant figures
Mass of NaCl = 525.98g NaCl
