Answer: 319.9g
Explanation:
Mass of graduated cylinder with water = 534.26g
Mass of graduated cylinder = 214.36g
Mass of just water = Mass of graduated cylinder with water - Mass of graduated cylinder.
Mass of just water = 534.26g - 214.36 g = 319.9g
Answer:
Molarity of 40 ml of NaoH is 0.3125 mL
Explanation:
As we know
Molarity of acid * volume of acid = molarity of base * volume of base
Substituting the given values, we get

Molarity of 40 ml of NaoH is 0.3125 mL
