Answer:

140 grams are needed!! Brrainliest??

Step-by-step explanation:

I multiplied this by the numbers needed How many grams of NaCl in 50 mL of 0.75 M NaCl solution? The MOLARITY of a solution is determined by the ratio of moles of solute, (the material being dissolved), compared to the liters of solution. the equation is M = mol L For this NaCl solution we have a Molarity of 0.75 in 50 mL of solution.
