C, because liquids as gas can move on there own at different points but solids are locked in place and do not move past one another like liquids and gases do.
Answer:
20%
Explanation:
mass by mass percentage of a solution =(mass of solute)/(mass of solution)
mass of solute=550g
therefore 110×100/550=20%

Answer:
139.94 grams of solute is present in kilograms of water
Explanation:
Temperature of the ice water = T = 1.0°C
Temperature of the mixture = 
=-3.0°C
Depression in freezing point 
=1.0°C-( -3.0°C)=4°C
m = molality of the solution
= Molal depression constant
Mole of solute = 0.1705 moles
Mass of solute = 11.1 g
Moles of solute = 
Molar mass of the solute= M
M = 65.088 g/mol
Molality of the solution = m = 
g of solute /kg of water
139.94 grams of solute is present in kilograms of water
Answer:
10573.9K
Explanation:
Using pressure law equation;
P1/T1 = P2/T2
Where;
P1 = initial pressure (mmHg)
P2 = final pressure (mmHg)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information provided in this question,
P1 = 46mmHg
P2 = 760mmHg
T1 = 640K
T2 = ?
Using P1/T1 = P2/T2
46/640 = 760/T2
Cross multiply
640 × 760 = 46 × T2
486400 = 46T2
T2 = 486400 ÷ 46
T2 = 10573.9K
