Answer:

The volume of the 0.76 M NaCl solution containing 0.35 g of NaCl is approximately 7.89 mL.

Step-by-step explanation:

To solve this problem, we need to use the relationship between the amount of solute (in moles), concentration (in molarity), and volume (in liters):

amount of solute (in moles) = concentration (in M) x volume (in L)

First, let's calculate the amount of NaCl in moles using the given mass and molarity:

moles of NaCl = mass of NaCl / molar mass of NaCl

moles of NaCl = 0.35 g / 58.44 g/mol (molar mass of NaCl)

moles of NaCl = 0.005992 mol

Next, we can use the above equation to solve for the volume of the solution:

0.005992 mol = 0.76 M x volume (in L)

volume (in L) = 0.005992 mol / 0.76 M

volume (in L) = 0.00789 L or 7.89 mL (rounded to three significant figures)

Therefore, the volume of the 0.76 M NaCl solution containing 0.35 g of NaCl is approximately 7.89 mL.
