1mol N2 + 3mol H2 → 2mol NH3
<span>Because you are dealing with gases, at the same temperature and pressure you can say: </span>
<span>1volume N2 + 3 volumes H2 → 2 volumes NH3 </span>
<span>OR: 4 volumes reactants = 2 volumes products. </span>
<span>You have 1.9+5.7 = 7.6 volumes reactants, which must give 7.6/2 = 3.8 volumes of NH3 </span>
<span>Answer: 3.8 litres of NH3 will be formed</span>
Answer:
There are 2.5 * 10^22 beryllium atoms in 0.37 grams
Explanation:
Step 1: Data given
The mass of an atom of beryllium is 1.5 x 10^-26 kg.
Total mass = 0.37 grams
Step 2: Calculate number of atoms
1 atom = 1.5 * 10 ^-26 kg
X atoms = 0.00037 kg
X = 0.00037/1.5*10^-26
X = 2.467 * 10^22 atoms ≈ 2.5 * 10^22 atoms
There are 2.5 * 10^22 beryllium atoms in 0.37 grams
