Question #152193
A solution of NaOH has a concentration of 7.5g/DM3.whatis the mass of NaOH contained in 500cm3?
Expert's answer
500 cm3 = 0.5 dm3
Solution:
Density = Mass / Volume
Mass = Density × Volume
Hence,
the mass of NaOH = 7.5 g/dm3 × 0.5 dm3 = 3.75 g
Answer: the mass of NaOH is 3.75 grams.
