Question

Write all the formula based on ,to find out moles... (structure of atom)..... ​

Answer 1

Answer:

$no. \: of \: moles (n)= \frac{given \: mass(m)}{molar \: mass(M.M.)}$

$n = \frac{given \: number \: of \: particles(N)}{avogadro \: no. (Na = 6.022 \times 10 {}^{23} )}$

$n = \frac{given \: volume \: of \: gas}{22.4 \: l} \: \: \: \: (at \: s.t.p.)$

Answer 2

Explanation:

In order to find no. of moles of substance we divide give given mass by molar mass of that compound

or if we knew the volume of compound we divide the given volume by 22.4litres

or if we r given no of atoms we divide no. of atoms by avagadro no. that is 6.022 ×10^23
