What is the molarity of the solution formed when 7.88 grams of nacl is mixed with enough water to make 350. ml of solution?

The molarity of the solution is 0.386 M

Explanation:

Step 1: Data given

Mass of NaCl = 7.88 grams

Volume of the solution = 350 mL

Molar mass of NaCl = 58.5 g/mol

Step 2: Calculate number of moles

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

Number of moles NaCl = 7.88 grams / 58.5 g/mol

Number of moles = 0.135 moles

Step 3: Calculate molarity of the solution

Molarity = Number of moles NaCl / volume

Molarity = 0.135 moles / 0.350 L

Molarity = 0.386 M

The molarity of the solution is 0.386M

h let me think

u i forgot the answer?
