The answer is:
the volume stays the same. it is the pressure that increases
The Hot water of the cofee is the SOLVENT, Sugar is the SOLUTE, and this means the sugar molecules must be HYDROPHILIC
Answer:
See below
Explanation:
Use Ideal Gas Law
PV = n RT using R = .082057366 l-atm/k-mol
T must be in Kelvin
solve for 'n'
.92 * 1.6 = n * .082057366 * 287
n = .0625 moles
then the mole weight: .0625 * x = .314
x = mole weight = 5.025 gm
"Systems with either very <u>low pressures or high temperatures</u> enable real gases to be estimated as “ideal.” "
Answer:
0.808 M
Explanation:
Using Raoult's Law
where:
= vapor pressure of sea water( solution) = 23.09 mmHg
= vapor pressure of pure water (solute) = 23.76 mmHg
= mole fraction of water
∴
------ equation (1)
------ equation (2)
where; 
number of moles of sea water
number of moles of pure water
equating above equation 1 and 2; we have :
NOW, Molarity = 
As we assume that the sea water contains only NaCl, if NaCl dissociates to Na⁺ and Cl⁻; we have
