If you have 2.4L of SO2 gas (at STP) how many moles of sulfur dioxide do you have?

Chemistry
1 answer:
Andru [333]3 years ago
4 0

Answer:

0.107 mole of SO2.

Explanation:

1 mole of a gas occupy 22.4 L at standard temperature and pressure (STP).

With the above information, we can simply calculate the number of mole of SO2 that will occupy 2.4 L at STP.

This can be obtained as follow:

22.4 L contains 1 mole of SO2.

Therefore, 2.4 L will contain = 2.4/22.4 = 0.107 mole of SO2.

Therefore, 0.107 mole of SO2 is present in 2.4 L at STP.

Leya [2.2K]
The side reaction will affect the purity and percent yield that, it will decrease the purity and also decrease the present yield.
Due to side reaction, the amount of aspirin which is being produced will be less for some amount of starting material which is used. The present yield will decrease. The insoluble water which is being precipitated is formed as a result of the side-reaction which will remain with aspirin and finally contaminate the aspirin.
The purity of aspirin will also decrease.

What is one characteristic of a rain forest?
Svetradugi [14.3K]
Different layers makes the most sense due to the fact it can’t be a dry climate because of the vegetation, also there is a lot of plants so minimal plants isn’t an option, and the temperature in a rain forest is usually very humid so cold temperatures can’t be an answer.

If the pH of a phosphoric acid (H3PO4) solution is adjusted to 6.50, what is the most abundant species and which is the second m
maria [59]

Explanation:

For the given values of K_{a} we will have the values of pK as follows.

As,        pK_{a} = -log K_{a}

Therefore,

     pK_{a1} = 2.15,     pK_{a2} = 7.20

      pK_{a3} = 12.38

Now, at pH 6.50

      H_{3}PO_{4} \rightarrow H_{2}PO^{-}_{4} + H^{+};   K_{a1}

At pH = 2.15;  H_{3}PO_{4} = H_{2}PO^{-}_{4}

       H_{2}PO^{-}_{4} \rightarrow HPO^{2-}_{4} + H^{+};  K_{a2}

At pH 7.20;  H_{2}PO^{-}_{4} = HPO^{2-}_{4}

        HPO^{2-}_{4} \rightarrow PO^{3-}_{4} + H^{+};     K_{a3}

Hence, we can conclude that most abundant species is H_{2}PO^{-}_{4} and the second most abundant species is HPO^{2-}_{4}.
