At 25.0 °C the Henry's Law constant for sulfur hexafluoride (SP) gas in water is 2.4x 10 M/atm Calculate the mass in grams of SF

Dmitry_Shevchenko [17]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The mass is $m = 0.0349 \ g$

Explanation:

From the question we are told that

The Henry's Law constant is $k = 2.4 *10^{10} M/atm$

The volume of water is $V = 525 \ ml = 0.525 \ L$

The partial pressure is $P = 1.90 \ atm$

The temperature is $T = 25 ^oC$

Henry's law is mathematically represented as

$C = P * k$

Where C is the concentration of sulfur hexafluoride(SP)

substituting value

$C = 1.90 * 2.4*10^{-4}$

$C = 4.56*10^{-4} \ M$

The number of moles of SP is mathematically represented as

$n = C * V$

substituting value

$n = 0.525 * 4.56*10^{-4}$

$n = 2.39 *10^{-4} \ moles$

The mass of SP that dissolved is

$m = n * Z$

Where Z is the molar mass of SP which has a constant value of

$Z = 146 g/mole$

$m = 2.394*10^{-4} * 146$

$m = 0.0349 \ g$

In a voltaic cell based on the Cu-Zn reaction

nata0808 [166]

Answer:

The quantities of electrical charge that are they can produce are the same

Explanation:

The quantity of electrical charge produced by an electrochemical cell is given by

Number of moles of electrons × Faraday's constant.

since the number of moles of electrons involved in the two electrochemical reactions are the same (2 moles of electrons each) then the charge that they can produce will also be the same.

Hence the answer.
