Answer:
2.05 liters

Calculate the molar mass of Ca(OH)2 =74.09g/mol

Calculate how many mol of Ca(OH) are in 64g

n=m/MM
n=64/74.09
n=0.86 mol

Calculate the volume of solution
M=n/V => V=n/M

V= 0.86 mol/ 0.420M
V= 2.05 liters

Answer:

30%

Explanation:

As the formula for finding concentration

= (mass of solute/mass of solution)×100

= (30/100)×100

= 0.3×100

= 30%

Consider the following equilibrium:
Colt1911 [192]

Answer:

a. If the reaction mixture initially contains only OF2(g), then at equilibrium, the reaction mixture will consist of essentially only O2(g) and F2(g).

Explanation:

The answer is a) because the value for Kp is really close to zero (having x10⁻¹⁵), this means that at equilibrium O₂ and F₂ will be significantly more present than OF₂.
