Answer 1

Step-by-step explanation:

hi friend.....

Since there are two moles of ammonium cations in one mole of ammonium dichromate, we multiply 18.039g/mol×2, which is equal to 36.078g/mol. To find the percentage of ammonium cations in ammonium dichromate, divide the total mass of the ammonium cations by the molar mass of ammonium dichromate and multiply times 100.

Answer 2

❤➡➡➡For every one formula there are two nitrogen atoms. 379g (NH4)2Cr2O7 A sample of ammonium dichromate contains 1.81 × 1024 nitrogen atoms.➡➡
