Answer: 67.23 L

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Putting in the values we get:

\text{Number of moles of methane}=\frac{48g}{16g/mol}=3moles

1 mole of methane occupies = 22.4 L

Thus 3 moles of methane occupy = \frac{22.4}{1}\times 3=67.23L

Thus volume of 48 grams of methane gas is 67.23 L

Calculate the ph of this solution. round to the nearest hundredth. poh = 3.45 ph =
maks197457 [2]

The potential of hydrogen pH of the solution with the given value of pOH to the nearest hundredth is 10.55.

What is pH of solution?

The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration  [H+] of the given solution.

It is expressed as;

pH = -log[ H⁺ ]

Also,

pH + pOH = 14

Given that;

  • pOH = 3.45
  • pH = ?

We simply substitute our values into the expression above.

pH + pOH = 14

pH + 3.45 = 14

pH = 14 - 3.45

pH = 10.55

Therefore, the potential of hydrogen pH of the solution with the given value of pOH to the nearest hundredth is 10.55.

How many total atoms does 3Na2S2O3 have
LUCKY_DIMON [66]

Answer:

21

Explanation:

Let us count the number of individual atoms for Na2S2O3 (the compound name):

Na: 2

S: 2

O: 3

This brings us to a total of 7 atoms for one molecule of sodium thiosulfate. For three of these compounds, we get 3*7=21
