The molecular formula of sucrose is - C₁₂H₂₂O₁₁
molecular mass of sucrose - 342 g/mol
molarity of sucrose solution is 0.758 M
In 1 L solution the number of sucrose moles are - 0.758 mol
Therefore in 1.55 L solution, sucrose moles are - 0.758 mol/L x 1.55 L
= 1.17 mol
The mass of 1.17 mol of sucrose is - 1.17 mol x 342 g/mol = 4.00 x 10² g
Answer:
Your answer could be: ceramic or stainless steel.
Explanation:
Glass, ceramic, and stainless steel are all good insulating materials for keeping coffee hot. Although, if you don't want to possibly burn yourself, don't use glass.
Have a great day/night! ^^
Answer : The partial pressure of X and Y gases are, 0.525 and 1.575 atm respectively.
Explanation : Given,
Moles of X = 2.0 mole
Moles of Y = 6.0 mole
Total pressure = 2.1 atm
Now we have to calculate the mole fraction of X and Y.
and,
Now we have to calculate the partial pressure of X and Y.
According to the Raoult's law,
where,
= partial pressure of gas
= total pressure of gas = 2.1 atm
= mole fraction of gas
and,
Thus, the partial pressure of X and Y gases are, 0.525 and 1.575 atm respectively.
