Answer:
yes
Explanation:
pls mark me brainliest right
Mass percent is the amount of solute per amount of solution times 100.
Mass percent = 3.75 mol / L ( 1L / 1230 g ) ( 98.08 g / 1 mol ) 100 = 27.86%
Molality is the amount of solute in moles per kilogram solution.
Molality = 3.75 mol/L ( 1 L / 1230 g ) (1000 g / 1 kg ) = 2.84 mol / kg
Mole fraction is the<span> amount of solute per amount of solution with units of moles.</span>
Answer:
Work is given by -PdV.
It clearly means that when volume of the system changes, work is done either on the system or by the system depending upon volume change.
So, pressure change term -VdP is not included because it is indicating a constant volume.
But in case of enthalpy,
H = U + PV
So, for enthalpy change we can write
dH = dU + PdV + VdP
Because enthalpy change is the sum of all energy changes in the system that includes internal energy, P-V work and effect of pressure change.
