Answer:
140 grams NaCl is needed
Step-by-step explanation:
i used this 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. Then i multiplied it by the correct amount
