A gaseous hydrogen and carbon containing compound is decomposed and found to contain 82.66% carbon and 17.34% hydrogen by mass.
Doss [256]
For the answer to the question above, I'll show the solution to my answers

moles C = 82.66 g/ 12.0111 g/mol=6.882 
<span>moles H = 17.34 g/ 1.008 g/mol=17.20 </span>

<span>17.20/ 6.882 =2.5 => H </span>
<span>6.882 / 6.882 = 1 => C </span>

<span>to get whole numbers multiply by 2 </span>
<span>C2H5 ( empirical formula Molar mass = 29.062 g/mol) </span>

<span>n = pV/RT = 0.732 x 0.158 L/ 0.08206 x 298 K= 0.00473 </span>
<span>molar mass = 0.275/ 0.00473 =58.1 g/mol </span>

<span>58.1 / 29.062 = 2 </span>

<span>multiply by two the empirical formula </span>

<span>C4H10</span>

Which two subatomic particles do you add together to determine the atomic mass or mass # of the atom?
raketka [301]

Answer:

Protons and Neutrons

Explanation:

The sum of number of protons and the number of neutrons is equal to the mass of an element. Mathematically, it can be given as :

M = P + N

Also, the atomic mass can be calculated by the sum of the element's isotopes as isotopes have slightly different mass numbers.

Hence, protons and neutrons add together to determine the atomic mass.
