ATP is an important molecule in living cells. A sample with a mass of

0.8138\,\text{g}

was analysed and found to contain

0.1927\,\text{g}

0.02590\,\text{g}

0.1124\,\text{g}

N, and

0.1491\,\text{g}

P. The remainder was oxygen. Determine the empirical formula of ATP. Its formula mass was found to be

507\,\text{g mol}^{-1}

. Determine its molecular formula. (a) Determine the empirical formula of ATP. (b) Determine the molecular formula of ATP.
