vertical, upright, erect, disinclined.
Answer:
The vapor pressure of the solution is 3.69 torr
Explanation:
Step 1: Data given
Mole fraction of benzene in the solution = 0.139
P° of benzene is 26.5 torr
Step 2: Calculate the vapor pressure of the solution
Psolution = Xbenzene * P°benzene
⇒with Psolution = the vapor pressure of the solution
⇒with Xbenzene = the mole fraction of benzene = 0.139
⇒with P°benzene = the vapor pressure of pure benzene = 26.5 torr
Psolution = 0.139 * 26.5 torr
Psolution = 3.69 torr
The vapor pressure of the solution is 3.69 torr
Answer: 10HSiCl3 + 15H2O → H10Si10O15 + 30HCl
Explanation:
Answer:
159.609 g/mol
Explanation:
According to the CuSO4.5H2O (k) heat CuSO4 (k) + 5 H2O (g) equation, the crystal water amount of copper sulfate and its rough formula will be calculated.
Weight of copper sulfate containing crystal water = m1 = 249.62… g
Weight of copper sulfate without crystal water weighed = m2 = 159.62 g
Accordingly, calculate the x and y values in the molecular formula of copper sulfate (xCuSO4.yH2O).
