Question

140 gm nitrogen gas how many miles

Answer 1

Explanation:

Answer:

Given mass = 140g

Atomic mass of Nitrogen = 28

\sf{number \: of \: moles \: = \dfrac{given \: mass}{atomic \: mass} }numberofmoles=

atomicmass

givenmass

or, n = 140/28

or, n. = 5

Therefore, number of moles is 5.

More equation for finding number of moles

\sf{n = \dfrac{molecular \: mass}{atomic \: mass}}n=

atomicmass

molecularmass

\sf{n = \dfrac{given \: volume}{22.4} }n=

22.4

givenvolume

\sf{n = \dfrac{no \: of \: particles}{6.022 \times {10}^{23} } }n=

6.022×10
