Calculate mass % of solution prepared using 12g NaOH & 90g water Also calculate its molality

Calculate mass % of solution prepared using 12g NaOH & 90g water Also

1.	Calculate mass % of solution prepared using 12g NaOH & 90g water Also calculate its molality
Answer» MASS %= 12/102×100 = 11.8 %no. of mole NaOH = 12/ MOLARS mass= 0.3molality= mole of solute/ mass of solutions in KG = 0.3/0.09(kg) = 33.3 m
