Check your chemistry textbook (or class notes) concerning molar mass, then look up the value for oxygen.
Then divide Avogadro’s number into the given amount of atoms, to find the number of moles.
Then combine this result appropriately with the molar mass, and voilà!
…Then reconsider posting homework questions without showing the work you have already done.
Answer:
Solidification (freezing)
Explanation:
This is the process whereby water or any liquid changes into solid.
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>
