The empirical formula of arginine is C3H7N2O2.

<h3>What is the empirical formula of arginine?</h3>

Now we know that the empirical formula is the formula that shows the ratio of the atoms present in the compound.

Now we know that;

C - 41.368/12    H -  8.101/1     N -  32.162/14    O - 18.369/16

C - 3.445           H -  8.101      N - 2.297           O - 1.148

Dividing through by the lowest ratio;

C - 3.445/1.148    H -  8.101/1.148    N - 2.297/1.148   O - 1.148/1.148

C - 3                   H - 7                     N - 2                   O - 2

C3H7N2O2

Is barium nitrate more soluble in water than CH4 or the other way around?
kenny6666 [7]
Barium nitrate and methane (CH4) are both soluble. They both will dissolve in water, however, barium nitrate will dissociate becoming barium 2+ ions and nitrate becoming NO3 1- ions. All nitrates are soluble and dissociate. CH4 is a weak base and does dissolves but doesn't dissociate. So in solubility terms.... they are both equally soluble just one happens to dissociate into its cations and anions. Hope this helps!
