A is the answer im pretty sure
Answer : The volume of solution will be, 0.309 L
Explanation : Given,
Mass of = 449.4 g
Molar mass of = 132 g/mole
Concentration = 11 M
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the volume of solution will be, 0.309 L
Answer:
[OH-] = 0,071 mol/L
Explanation:
pOH = -log[OH-]
[OH-] = 10^-pOH = 10^-1.15 = 0,071 mol/L
Hg2O -> O2 + Hg
2Hg2O -> O2 + 2Hg
20g-> ?g + 18.6g
(1 molHg2O ) (1 mol O2) (32g O2)
20g 2Hg2O x ------------------- x ------------------- x -------------- = 0.77g O2
(834.36Hg2O) (1 mol Hg2O) (1 mol O2)
