because of the law of conservation of energy...
Molar mass of C6H8O7 = 12*6 + 1*8 + 16*7 = 72 + 8 + 112 = 192 u.
To convert grams to moles, you need to divide the given mass by the molar mass of the substance. The molar mass of NaCl (sodium chloride) is 58.44 g/mol. Therefore, 11.2 grams of NaCl would be equal to 0.191 moles.
To calculate the number of moles in 100mg of citric acid (C6H8O7), first determine its molar mass by adding up the atomic masses of each element: C(12.01) + H(1.01) + O(16.00) x 7. Convert 100mg to grams (0.1g) and then divide the mass by the molar mass of citric acid to find the number of moles.
First we find the molar mass of citric acid (C6H8O7): (612.01 g/mol) + (81.01 g/mol) + (7*16 g/mol) = 192.13 g/mol Next, we calculate the number of moles in 192 g: 192 g / 192.13 g/mol ≈ 1 mol Finally, using Avogadro's number, we find the number of molecules in 1 mol: 1 mol * 6.022 x 10^23 molecules/mol = 6.022 x 10^23 molecules
I do not see an isotope of iridium that does alpha decay. There is an interactive link to isotopes below. (Perhaps I am missing it.)

1923 = 192 x 192 x 192 = 7077888
75% of 192= 75% * 192= 0.75 * 192= 144
192
10% of 192 = 10% * 192 = 0.1 * 192 = 19.2
1922 = 192 x 192 = 36,864
20 percent of 192 = 38.4 20% of 192 = 20% * 192 = 20%/100% * 192 = 384/10 or 38.4
192
Exactly as in the question 192
