Answer:

[Na₂CO₃] = 0.094M

Explanation:

Based on the reaction:

HCO₃⁻(aq) + H₂O(l) ↔ CO₃²⁻(aq) + H₃O⁺(aq)

It is possible to find pH using Henderson-Hasselbalch formula:

pH = pka + log₁₀ [A⁻] / [HA]

Where [A⁻] is concentration of conjugate base,  [CO₃²⁻] = [Na₂CO₃] and  [HA] is concentration of weak acid, [NaHCO₃] = 0.20M.

pH is desire pH and pKa (<em>10.00</em>) is -log pka = -log 4.7x10⁻¹¹ = <em>10.33</em>

<em />

Replacing these values:

10.00 = 10.33 + log₁₀ [Na₂CO₃] / [0.20]

<em> [Na₂CO₃] = 0.094M</em>

<em />

The volume noted in the figure(9.583 L) contains nitrogen gas under a pressure of 4.97atm at 19.71°C. Calculate the number of mo
garri49 [273]

Answer:

The number of moles of nitrogen in the tank are 1,98.

Explanation:

We apply the ideal gas law, convert the temperature unit in Celsius to degrees Kelvin, solve for n (number of moles). The gas constant R is used with a value of 0.082 l atm / K mol:

0°C= 273 K ---> 19, 71°C= 273 + 19,71= 292, 71K

PV= nRT ---> n=PV/RT

n= 4,97 atm x 9,583 L/ 0.082 l atm / K mol x 292, 71K=<em> 1, 98 mol</em>
