Consider the following reaction: CO(g)+2H2(g) &lt;--&gt; CH3OH(g).
Andrew [12]

Answer:

123 is the equilibrium constant for the reaction.

Explanation:

CO(g)+2H_2(g)\rightleftharpoons CH_3OH(g)

Equilibrium concentration of reactants :

[CO]=0.115 M,[H_2]=0.116 M

Equilibrium concentration of products:

[CH_3OH]=0.190 M

The expression of an equilibrium constant is given by :

K_c=\frac{[CH_3OH]}{[CO][H_2]^2}

K_c=\frac{0.190 M}{0.115 M\times (0.116 M)^2}

K_c=122.78 \approx 123

123 is the equilibrium constant for the reaction.

Olive oil has a density of 0.92 g/mL. How much would 1 liter of olive oil weigh in grams?
svp [43]
Dimension analysis is to be used to solve this problem. First convert 1L to milliliters. That is equivalent to 1000 ml. Then by dimension analysis, multiply the volume ( 1000ml) to the density of oil (0.92 g/ml) resulting to the answer: 920 grams.
