Answer:
The correct answer is - 2.107 x 10^24 mango seeds.
Step-by-step explanation:
Given:-
number of moles of mango seeds = 3.50 mol
Solution:-
1 mol of mango seeds = 6.02 x 10^23 mango seeds
6.02 x 10^23 is Avagadro numbers
1 mole is the number of particles contained in a substance . The number of moles can also be calculated by dividing the mass by the molar mass of the element or molecule of the substance with the Avogadro's number.
Therefore,
3.50 mol of mango seeds = 3.50 x 6.02 x 10^23 mango seeds
3.50 mol of mango seeds = 21.07 x 10^23 mango seeds
3.50 mol of mango seeds = 2.107 x 10^24 mango seeds
