What is the molarity in 750.ml of solution containing 65 grams of NaCl

1.48 M

Explanation:

Molarity(M) is the unit that measures how many moles of solute every one liter of solvent. Another unit that can be used beside molarity is molality(m), which measures how many moles of solute every one kilogram of solvent. Molarity used a lot but molality can be more accurate if the temperature of the solution changes a lot.

There are 750ml of solvent and 65 grams of solute. If the molecular mass of NaCl is 58.44, the molarity of the solution will be: (65gram /58.5g/moles) / (750ml * 1 L/ 1000ml)= 1.48 M

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
