First, we use avogadro's number to convert atoms into moles. Then, relate the number of moles from elemental to the compound. Lastly, we use conditions at STP to calculate the volume. We do as follows:
<span>9.86 x 10²⁸ O-atoms ( 1 mol / 6.022x10^23 atoms O) ( 1 mol N2O2 / 2 mol O ) ( 22.4 L / 1 mol ) = 1833809.37 L needed</span>

Explanation:
Answer:
2 groups
Explanation:
The molecule 3, 3-diethylpentane has 2 ethyl groups because the prefix di- means that there are 2 homogeneous substituent groups present in the molecule.
Answer: 0.100 m
Explanation:
Elevation in boiling point is given by:
= Elevation in boiling point
i= vant hoff factor
= boiling point constant
m= molality
1. For 0.100 m
, i= 3 as it is a electrolyte and dissociate to give 3 ions. and concentration of ions will be
2. For 0.100 m
, i= 2 as it is a electrolyte and dissociate to give 2 ions, concentration of ions will be
3. For 0.200 m
, i= 1 as it is a non electrolyte and does not dissociate, concentration of ions will be
4. For 0.060 m
, i= 4 as it is a electrolyte and dissociate to give 4 ions. and concentration of ions will be
Thus as concentration of solute is highest for , the elevation in boiling point is highest and thus has the highest boiling point.
