What mass (in g) of NH3 must be dissolved in 475 g of methanol to make a 0.250 m solution?

Tema [17]

Answer:

We need 2.02 grams of NH3

Explanation:

Step 1: Data given

Mass of methanol = 475 grams

Molality of the solution = 0.250 M

Molar mass of NH3 =17.03 g/mol

Molar mass of = methanol = 32.04g/mol

Step 2: Calculate moles NH3

Molality = 0.250 m = mol NH3 / 0.475 kg

moles NH3 = 0.250 molal * 0.475 kg

Moles NH3 = 0.11875 moles

Step 3: Calculate the mass of NH3

Mass NH3 = moles NH3 * molar mass NH3

Mass NH3 = 0.11875 mol * 17.03 g/mol

Mass NH3 = 2.02 grams

We need 2.02 grams of NH3

Problem PageQuestion Iron(III) oxide and hydrogen react to form iron and water, like this: (s)(g)(s)(g) At a certain temperature

Marrrta [24]

Complete question

The complete question is shown on the first uploaded image

Answer:

The value is $K_c = 2.69 *10^{-5}$

Explanation:

From the question we are told that

The equation is

$Fe_20_3_{(s)}+3H_{(g)}\to2Fe_{(s)}+3H_2O_{(g)}$

Generally the equilibrium is mathematically represented as

$K_c = \frac{[H_2O]^2}{[H_2]^3}$

Here $[H_2O]$ is the concentration of water vapor which is mathematically represented as

$[H_2O ] = \frac{n_w}{V_s }$

Here $V_s$ is the volume of the solution given as 8.9 L

$n_w$ is the number of moles of water vapor which is mathematically represented as

$n_w = \frac{m_w}{Z_w}$

Here $m_w$ is the mass of water given as 2.00 g

and $Z_w$ is the molar mass of water with value 18 g/mol

So

$n_w = \frac{2}{18}$

=> $n_w = 0.11 \ mol$

So

$[H_2O ] = \frac{0.11}{8.9 }$

=> $[H_2O ] = 0.01236 \ M$

Also

$[H]$ is the concentration of hydrogen gas which is mathematically represented as

$[H ] = \frac{n_v}{V_s }$

Here $V_s$ is the volume of the solution given as 8.9 L

$n_v$ is the number of moles of hydrogen gas which is mathematically represented as

$n_v = \frac{m_v}{Z_v}$

Here $m_w$ is the mass of water given as 4.77 g

and $Z_v$ is the molar mass of water with value 2 g/mol

So

$n_w = \frac{4.77}{2}$

=> $n_w = 2.385 \ mol$

So

$[H_2O ] = \frac{2.385}{8.9 }$

=> $[H_2O ] = 0.265 \ M$

So

$K_c = \frac{( 0.01236 )^3}{ (0.265 )^2}$

=> $K_c = 2.69 *10^{-5}$
