Please! Answer ANYTHING u can!



1. Nitroglycerine contains 60% as many carbon atoms are hydrogen atoms, three times as many oxygen atoms as nitrogen atoms, and the same number of carbon and nitrogen atoms. the number of moles of nitroglycerine in 1.000 grams is 0.00441 moles. What is the molecular formula of nitroglycerine?


2. Avogadro's number has been determined by about twenty different methods. In one approach, the spacing between ions in an ionic substance is determined by using a technique called X-Ray diffraction. X-Ray diffraction studies of sodium chloride has shown that the distance between adjacent Na+ and Cl- ions is 2.819 x 10-8 cm. The density of solid NaCl is 2.165 g/cm

By calculating the molar mass to four significant figures, you can determine Avogadro's number. What value do YOU obtain?

Thank you! Have a beautiful day!
