Note: You are calculating mass which is determine the gram(g)
You will have to cancel out the mol
(28.97 g/mol) * mol will give grams by itself
Given the mass 3.33 moles of air
28.97 g/mol * 3.33 mol = 96.47 grams
Solution: 96.5 grams

Carbon exists in nature as three isotopes. Given the atomic masses and relative abundance of the isotopes, what is the average a
Ivan

The most abundant carbon isotope is carbon-12.

The relative atomic mass of carbon is 12.011, which is extremely close to 12.0. This means that the masses C-13, and C-14 are practically negligible when contributing to the relative atomic mass of carbon.

the C-12 isotope makes up 98.9% of carbon atoms, C-13 makes up 1.1% of carbon atoms, and C-14 makes up just a trace of carbon atoms as they are found in nature.

23491pa undergoes beta decay. what is the mass number of the resulting element?
qaws [65]
Answer is: mass number is 234.
Beta decay is radioactive decay<span> in which a </span>beta ray<span> and a </span>neutrino<span> are emitted from an </span><span>atomic nucleus.
</span>There are two types of beta decay: beta minus<span> and </span>beta plus. <span> In beta minus </span><span>decay, neutron is converted to a proton and an </span>electron<span> and an </span>electron antineutrino and in beta plus <span>decay, a proton is converted to a neutron and </span>positron<span> and an </span>electron neutrino, so mass number does not change.

Chlorine gas reacts with aluminum metal producing aluminum chloride. What mass of chlorine reacts with 9.00g of Al to form AlCl3
Anit [1.1K]
The  mass of  chlorine   that react  with  9.00 g  of Al to form AlCl3  is   35.465  grams

     Explanation
write  the equation  for  reaction
that is
2 Al +  3 Cl2  = 2 Al CL3
find  the moles  of    Al  reacted

moles = mass/molar mass

  9 g/ 27  g/mol = 0.333  moles  of Al

by use  of mole ratio between   Al to  Cl2    which is  2:3   find the moles of  Cl2

mole  of cl2 =  0.333 x3/2 = 0.4995  moles


mass of  Cl2  is therefore =  moles  x  molar mass

= 0.4995  x71 =  35.465  moles
