Answer:
moles of carbon
Explanation:
1 trillion = 
Avogadro number :It is the number of particles that are present in 1 mole of substance.
So,
atoms = 1 mole carbon
1 atom =
mole
1 trillion atom =
mole
mol
Two significant figure
moles of carbon

Answer:
The electronegativity differences between carbon and oxygen are not very large.
Explanation:
Between the atoms of carbon monoxide exists a covalent bond which attaches the carbon to the oxygen.
In this type of bonding, both atoms shares a given number of valence electrons to attain chemical stability.
A substance is polar when there is a distinct charge separation between the species.
For covalent bonds, the electronegativity difference plays in important role in determining the polarity of the compound. When the difference is large, the compound will be polar but when the difference is very small or zero, no polarity will exist.
In between carbon and oxygen of carbon monoxide, the electronegativity difference is very low.
Answer: The density of kerosene is 
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of kerosene = mass of beaker with kerosene - mass of empty beaker = 60 g - 20 g = 40 g
Volume of kersone = 
Putting in the values we get:
Thus the density of kerosene is
