Answer:
3.50 moles of many mango seeds = 2.107.10²⁴ mango seeds
Further explanation
A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12
While the number of moles can also be obtained by dividing the mass (in grams) with the molar mass of element or molecule
With Avogadro's number
N = number of gas particles
No = Avogadro number (6.02.10²³)
n = number of moles
\rm n=\dfrac{N}{No}n=
No
N
3.50 moles of many mango seeds are comparable to:
\begin{gathered}\rm N~mango~seeds=3.5\times 6.02.10^{23}\\\\N~mango~seeds=\boxed{\bold{2.107\times 10^{24}}}\end{gathered}
N mango seeds=3.5×6.02.10
23
N mango seeds=
2.107×10
24
