The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. To calculate the relative atomic mass of chlorine, the average mass of one atom of chlorine is found by considering 100 atoms of chlorine.
You can find the relative atomic mass by adding the number of protons to the number of neutrons for specific consideration. For example, a carbon-12 atom has 6 protons and 6 neutrons, and so has a relative atomic mass of 12.

Answer: True
Explanation:
Scientists are not supposed to include their personal opinions in their results, it voids the validity of the entire experiment.
Answer:
The solution to the question is as follows
(a) The rate of ammonia formation = 0.061 M/s
(b) the rate of N₂ consumption = 0.0303 M/s
Explanation:
(a) To solve the question we note that the reaction consists of one mole of N₂ combining with three moles of H₂ to form 2 moles of NH₃
N₂(g) + 3H₂(g) → 2NH₃(g)
The rate of reaction of molecular hydrogen = 0.091 M/s, hence we have
3 moles of H₂ reacts to form 2 moles of NH₃, therefore
0.091 M of H₂ will react to form 2/3 × 0.091 M or 0.061 M of NH₃
Hence the rate of ammonia formation is 0.061 M/s
(b) From the reaction equation we have 3 moles of H₂ and one mole of N₂ being consumed at the same time hence
0.091 M of H₂ is consumed simultaneously with 1/3 × 0.091 M or 0.0303 M of N₂
Therefore the rate of consumption of N₂ = 0.0303 M/s

Answer:
12.6 L CO2
Explanation:
Mass = 24.7 grams
Molar mass = 44.01 g/mole
Volume at STP = ?
The relationship between these quantities is given as
Number of moles = Mass / Molar mass
Number of moles = 24.7 g / 44.01 g/mole
Number of moles = 0.5612 moles
1 mol = 22.4 L
0.5612 mol = x
x = 0.5612 * 22.4
x = 12.6 L
