El gas se puede medir por volumen en cm3 utilizando un instrumento conocido como eudiómetro.
Answer:
Mass ratio: 71:112
Atomic ratio: 2:7
Explanation:
1. To get the mass ratio of of the compound Cl2O7, the following steps are followed:
- The atomic mass of Cl = 35.5g/mol, O = 16g/mol
- The mass of each element in the compound is as follows:
Cl2 = 35.5(2) = 71g
O7 = 16(7) = 112g
The mass ratio is the ratio of one mass of an element to another in the compound, hence, the mass ratio is 71:112
- The molar mass of the compound, Cl2O7, is determined:
71 + 112 = 183g/mol
- The mass percent of each element is determined by dividing the mass of each element present by the Molar Mass:
Cl = 71/183 = 0.3879 × 100 = 38.8%
O = 112/183 = 0.612 × 100 = 61.2%
2. Atomic ratio is the ratio of one atom in a molecule to another. It can be calculated this:
In Cl2O7, there are 9 total atoms (2 atoms of Cl + 7 atoms of oxygen).
Hence, that atomic ratio of Cl to oxygen in Cl2O7 is 2:7
