Answer:
The required volume is 1.12 L.
Explanation:
Given,
Mass of O2 gas= 1.60 grams
We know,
Number of moles = Mass/Molecular mass
= 1.60/32 [Molecular mass of O2 gas is 32 gram]
= 0.05
Again,
We know that at STP,
Number of moles = Volume in L / 22.4 L
or, Volume = Number of moles X 22.4
or, Volume = 0.05 X 22.4
or, Volume = 1.12
∴The required volume is 1.12 L.

plz mark me as brainliest.
The easiest way to answer this question is to first figure out the molar mass of the sugar in question. To do this multiply the number of individual atoms for a given element by its atomic mass. 12 X 12.01 g/mol = 144.12 g/mol C. 22 X 1.008 g/mol = 22.176 g/mol H. 11 X 16.00 g/mol = 176.00 g/mol O.
