How much mass of carbon dioxide gas contains equal number of 2
molecules as 36 gram of water vapour contains ?
Answers
Answer:
m = 55gram
Explanation:
molar mass of co2 = 12 + 2 × 16 = 44g
molar mass of o2 = 2 × 16 = 32g
number of molecules in 32g oxygen = Nà
number of molecules in 40g oxygen = 40/32 × Na
Given: molecule in 40g oxygen = molecules of mass of carbon dioxide
m/44 × Na = 40/32 × Na
m/44 = 40/32
m = 55g
Answer:
The mass of carbon dioxide gas contains an equal number of molecules as 36 grams of water vapor = 88 grams of carbon dioxide.
Explanation:
Given the mass of water vapor = 36 gram
The molecular mass of water = 18g/mol
Number of moles of water molecules present = 2
The molecular mass of carbon dioxide = 44 g/mol
Therefore the mass of carbon dioxide = 44×2 = 88 gram
The mass of carbon dioxide gas contains an equal number of molecules as 36 grams of water vapor = 88 grams of carbon dioxide.
