Juli2301 [7.4K]

The formula that connects Ka1, Ka2, and Ka3 is the relation;

Ka = Ka1 * Ka2 *  Ka3

<h3>What is the Ka?</h3>

The Ka is defined as the acid dissociation constant of a solution. Now we have the triprotic acid called phosphoric acid. this implies that we have Ka1, Ka2, and Ka3.

Thus the formula that connects Ka1, Ka2, and Ka3 is the relation;

Ka = Ka1 * Ka2 *  Ka3

A flask contains 5.0g of neon gas at a temperature of 35°C. The pressure gauge indicates 0.37atm inside the flask. What is the v
DaniilM [7]

Answer:

The volume of the neon gas is 17.07 L.

Explanation:

The ideal gas equation describes the relationship among the four variables  P, V, T, and n. An ideal gas<u> is a hypothetical gas whose pressure-volume-temperature  behavior can be completely accounted for by the ideal gas equation</u>.

In order to calculate the volume, first we need to convert the grams of neon to moles:

28.18 g Ne ------ 1 mol Ne

5.0 g Ne---------- <u>x= 0.25 mol Ne</u>

Now, using the ideal gas equation we calculate the volume:

pV= nRT

V= nRT ÷ p

V= (0.25 mol × 0.082 L.atm/mol.K × 308.15 K ÷ 0.37 atm

V= 17.07 L
