Answer:
I think beaker three will take longer to boil since there is more water present,compared to the other beakers
D = m / V
d = 1300 g / 743 cm³
d = 1.749 g/cm³
The change of phase from a vapor to a liquid is called condensation.

Answer: short answer short 0.65 / 5.37
15% NaOH by mass is 15g of NaOH in (100-15)g of solution.
No. Of moles of NaOH in solution = 0.65
No of moles of Water in solution = 4.72
Mole Fraction =
(
(Moles of Solvent)
(Moles Of Solute)+(Moles of Solvent)
)
OR
(
(Moles of Solvent)
Total Number Of Moles
)
= 0.65 / 5.37
= 0.121
