Also contain ribosomes (in the cytoplasm), floating freely or attached to membranes called rough endoplasmic reticulum. Ribosomes are responsible for protein synthesis and enzymes involved in respiration

Ответ:
D=density at STP = molar mass / 22.4
dNe = 20/22.4=0.89
dO2= 2*16/22.4=1.42
dF2=2*18/22.4=36/22.4=1.60
dCl3=3*35.5/22.4=4.75
in order of decreasing density at STP means
dNe <dO2 <dF2<dCl3
