Ammoniumphosphate (NH4)3PO4Using the results from problems 5-8, calculate the amount of hydrogen, in grams, in the following amounts of these compounds.Hint: Multiply the percentage of Hydrogen in each substance by the number of grams given. For example, if the percent of hydrogen in #5 was 25% (just using this as an example) multiply 350 x 25/100 to get the number of grams of hydrogen in #9.9. 350 gC10H14O XXXXXXXXXXgNa2C4H4O611.124 gCa(HC2O4)2 XXXXXXXXXXg(NH4)3PO4Which of the following compounds has the highest percentage of iron content?13.

1. 60.2g of Hg combines completely with 24.0g of Br.
Ans: Hg=60.2g and Br 2 24.0g as mas 
(HgBr2)= 60.2+24.0
= 84.2g or Hg= Hg/(HgBr2)*100
= 60.2/84.2g * 100% or 71.5% of Hg.
2. 0.219g of La reacts with Oxygen to form a compound with a mass of 0.256.g
Ans:  La moles =0.219g/138.906g/mol= 0.00158 
         O moles= 0.256-0.219/15.999g/mol= 0.00231
0.00231/0.00158=1.5 for O and 0.00158/0.00158= 1 for La if we multiply by 2 or 50 percentage could get the calculative number- 
La2O3
3. 0.875g of Al combines completely with 3.45g of Cl.
Ans: Al moles= 0.875g/26.981 g/mol= 0.0324 
      Cl= 3.45g/ 35.45 g/mol= 0.0973 
AlCl3= 0.0324+0.097*3
         = 0.0324+0.292*100 or 29.3%
4. 4.29g of C combines completely with 5.71g of O.
Ans: C moles= 4.29g/ 12.01 g/mol= 0.357 
      O= 4.71g/ 15.99 g/mol= 0.294 
CO2= 0.357+0.294*2
         = 0.357+0.589*100 or 94.61%
