How many molecules in 0.63 moles

The answer fr the following problem is mentioned below.

Explanation:

Given:

no of moles (n) = 0.63 moles

We know;

no.of molecules at STP condition ()= 6.023 ×10^23

To solve:

no of molecules(N)

We know;

to calculate no of molecules present,the formula is mentioned below as follows:

From the ideal gas equation,

n = N ÷

where,

n = no of moles

N = no of molecules

= no of molecules at STP conditions(Avogadro number)= 6.023 ×10^23 molecules

0.63 = N ÷ 6.023 ×10^23

N = 0.63 × 6.023 × 10^23

N = 3.79449 × 10^23 molecules

Therefore no of molecules present are 3.79449 × 10^23 molecules

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )
