As the volume increases, there is more space so the average distance between the gas molecules also increases.
Answer:
Mass of HCl = 73 g
Explanation:
Given data:
Mass of hydrogen = 2 g
Mass of HCl = ?
Solution:
First of all we will write the balance chemical equation:
H₂ + Cl₂ → 2HCl
Number of moles of hydrogen = 2 g/ 2g/mol
Number of moles of hydrogen = 1 mol
Form balanced chemical equation compare the moles hydrogen with HCl.
H₂ : HCl
1 : 2
Mass of HCl:
Mass of HCl = number of moles × molar mass
Mass of HCl = 2 mol × 36.5 g/mol
Mass of HCl = 73 g
Given that in the alien planet the names of substances and the units in which they are measured in not familiar.
8 quibs of a substance called skvarnik is present.
The conversion factor between sleps and quibs is: 9 sleps = 13 quibs
Converting 8 quibs of skvarnick to sleps:
5.54 when rounded to nearest tenth becomes 5.5.
So the correct answer would be 5.5
