At the boiling point, external pressure is equal to the vapor pressure of water. Therefore, the vapor pressure of water at an ecternal pressure of 404 kPa is equal to 404 kPa as well. Hope this answers the question. Have a nice day. Feel free to ask more questions.
Answer:
H₄SiO₄
Explanation:
From the question given above, the following data were obtained:
Hydrogen (H) = 4 moles
Oxygen (O) = 4 moles
Silicon (Si) = 1 mole
Empirical formula =?
Since the number of mole of each atom of the element present is known, the empirical formula of the compound can be written as follow:
H₄SiO₄
Answer:
0.125
Explanation:
no of moles = given mass / molar mass
no of moles = 7/
molar mass of calcium oxide = atomic mass of calcium + oxygen
molar mass = 40 + 16
molar mass = 56
no of moles = 7/ 56 = 1/8 = 0.125
