Answer:
50 moles of many mango seeds = 2.107.10²⁴ mango
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
n= N/No
3.50 moles of many mango seeds are comparable to
N mango seeds= 3.5 x 6.02.10²³
N mango seeds=2.107 x 10²⁴..
