Calculate the number of molecules in 0.5 mol of sulfur dioxide, SO2. Describe what is meant by a mole of sodium atoms. I need answers ASAP

We know, 1 mole of any element/compound contains 6.022 × 10²³ atoms/molecules .

Now, we have to calculate the number of molecules in 0.5 mole of sulfur dioxide, SO₂.

So, number of molecules of SO₂ in 0.5 mole is :

Therefore, number of molecules in 0.5 mole of SO₂ is 3.011 × 10²³.

the energy to form plasma comes from heat or electricity in the atmosphere!

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
