A urine sample has a mass of 147 g and a density of 1.020 g/mL. What is the volume of this sample?

son4ous [18]

So we know that the equation for density is:

$D=\frac{m}{V}$

where D is the density, m is the mass in grams, and V is the volume in mL.

So since we know two of the variables, mass and density, we can solve for the volume:

$\frac{1.020g}{mL}=\frac{147g}{V}$

$V=\frac{147g}{\frac{1.020g}{mL}}$

$V=144.12mL$

Therefore, the volume of this urine sample is 144.12mL.

Consider the following chemical reaction: CO (g) + 2H2(g) ↔ CH3OH(g) At equilibrium in a particular experiment, the concentratio

grigory [225]

Answer : The equilibrium concentration of $CH_3OH$ will be, (C) $2.82\times 10^{-1}$

Explanation : Given,

Equilibrium constant = 14.5

Concentration of $CO$ at equilibrium = 0.15 M

Concentration of $H_2$ at equilibrium = 0.36 M

The balanced equilibrium reaction is,

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

The expression of equilibrium constant for the reaction will be:

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

Now put all the values in this expression, we get:

$14.5=\frac{[CH_3OH]}{(0.15)\times (0.36)^2}$

$[CH_3OH]=2.82\times 10^{-1}M$

Therefore, the equilibrium concentration of $CH_3OH$ will be, (C) $2.82\times 10^{-1}$
