Question

The density of carbon dioxide is equal to 1.965 kgm^(-3) at 273 K and 1 atm pressure. Calculate the molar mass of CO2

Which contains the greatest number of moles of oxygen atoms
* I mol of ethanol
* 1 mol of formic acid
* 1 mol of H2O

With explanations
I will mark it as brainliest ​

Answer 1

Answer:

$co {} {2} = 1.965 \: kgm ^{3 \: } at \: 273k$

law of conservation of co2=1.965

12+16×2=1. 965

=1. 965/44

=0.04

one mole atom= 273/0.04

=6,825
