Density of NaOH
= Mass / Volume
= (15 g) / (20 ml)
= 7.5 g/ml
= Mass / Volume
= (15 g) / (20 ml)
= 7.5 g/ml

again... This can't possibly be a serious question.

you and your 2 followers (i.e YOU with your Micatkie account and YOU with your 2 duplicate accounts) missed the fact that 15 / 20 ≠ 7.5. you're off by a factor of 10.... oops
btw... no one here pays any attention to how many thumbs up you give yourself. You're wasting your time.

we know
density = mass / volume
so the density = mass / volume = 15 g / 20 ml = 0.75 g/ml.
density = mass / volume
so the density = mass / volume = 15 g / 20 ml = 0.75 g/ml.
