Answer:
15 moles.
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Clearly, since carbon and oxygen are in a 1:1 molar ratio, 15 moles of carbon will completely react with 15 moles of oxygen, therefore 15 moles of oxygen remain as leftovers. In such a way, since carbon and carbon dioxide are also in a 1:1 molar ratio, the theoretical yield of carbon dioxide is 15 moles based on the stoichiometry:
Best regards.
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
