The number of protons in a mango depends on the mass of the mango, and then it depends on how accurate you want the answer. A proton is a hydrogen atom. As a first estimate, most of the mango is water. If it was ALL water then (as in 18g of water there is 2g of hydrogen and 16g of oxygen) then 1/9 of the mass would be hydrogen. 6 x 1023 = 600,000,000,000,000,000,000,000 . This very big :} number is called a mole and it's the number of protons in a gram, roughly. Each gram of hydrogen contains 6 x 1023 atoms, so 9g of mango with 1g of hydrogen contains 6 x 1023 protons. So, weigh your mango in grams, divide the weight by 9, and multiply that by 6 x 1023 to get the number of protons.
