Answer:
carbon atoms tend to make four bonds, each carbon atom will have the number of hydrogen atoms that are required for four bonds. This compound contains 16 hydrogen atoms for a molecular formula of C 8 H 16.
Explanation:
1) Calculate the volume from d = m/V => V = m/d = 2.0*10^-23 g / 1.0*10^14 g/cm^3 = 2.0*10^-9 cm^3
2) Now use the formula of volume for a sphere: V = (4/3)π(r^3) =>
r =∛[3V/(4π)] = ∛[(3*2.0*10^-9 cm^3) / (4π)] = 0.48*10^-3 cm = 4.8*10^-4 cm = 0.00048cm
To be honest answer might be a
Explanation:
Just a few things to remember:
-
# of neutrons = Mass number - # protons
-
Mass number = # protons + # neutrons
-
Atomic Number = # of protons
- # of electrons = # of protons - charge on the atom
-
Symbol - use the atomic number to find the element in the periodic table
