What is the number of moles of solute in a 0.3 molal solution containing 0.10 kg of solvent? Don't forget the unit.
timurjin [86]
Molality is one way of expressing concentration for solutions. It has units of moles of solute per kg of solvent. From the given values, we easily calculate for the moles of solute by multiplying the mass of solvent to the molality. We do as follows:

moles solute = 0.3 (10) = 3 mol solute

When the [H+] in a solution is 1.7 × 10−9 M, what is the pOH ? 8.80 5.23 14 8.60
kumpel [21]
PH = -log[H+]
pH = -log[1,7×10^-9]
pH = 8,77

pH + pOH = 14
pOH = 14 - 8,77
pOH = 5,23
