Length of 1 side 1.2*10^-5km =1.2*10^-5*10^5 =1.2cm
<span>volume of the cube (1.2)^3=1.728 cm^3 </span>
<span>density= mass/volume= 1.1/1.728=0.636 g/cm^3</span>
6 moles to equal that I do t know for sure though

A safety guide lines are rules and regulations that are made to make sure place is safe and conducive for everyone.
Answer:
0.30M HOAc
Explanation:
Given 250.0ml (0.96M HOAc) => 800ml(??M HOAc)
Use the dilution equation...
(Molarity x Volume)concentrated soln = (Molarity x Volume)dilute soln
(0.96M)(250.0ml) = (Molarity diluted soln)(800ml)
Molarity diluted soln = (0.96M)(250.0ml)/(800ml) = 0.30M HOAc
Boiling point is the temperature at which vapour pressure equals atmospheric pressure.
As, we move at higher altitudes, atmospheric pressure decreases. Hence, temperature to reach the boiling point will decrease.
Further, boiling point is higher for longer chain compounds. Hence,<span> octane (C8H18) and octanol (C8H17OH) will have higher boiling point as compared to hexane (C6H14). Further, intermolecular forces of interaction are more stronger in octanol, due to presence of OH group, as compared to octane.
Hence, boiling points will be in following order:
Octanol > Octane > Hexane
Thus, hexane will boil first, followed by octane and lastly octanol.</span>
