How many mongo seed are equal to 3.50 moles of mongo seeds?​

The correct answer is - 2.107 x 10^24 mango seeds.

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

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
