multipy 160 by 10
Answer:
Explanation:
A carbon atom has 6 protons and 6 neutrons. This equals 12.000u & 1u is one-twelfth the mass of an atom of carbon. 1u =1.661x10^-24g so 6 protons plus 6 neutrons should equal the carbon-12 atom in grams and this divided by 12 should equal 1u =1.661x10^-24g proton weight in grams (1.672622 x 10^-24g) neutron wight in grams (1.674927 x 10^-24g) 1.672622 x 6 + 1.674927 x 6 ------------------- 20.085294g divide this by 12 = 1.67 x 10^-24g I wonder whether i am doing something wrong or my numbers are inaccurate but this can't be as in the book it mentons 1.661x10^-24g right before it gives the proton and neutron masses, can someone explain how 1.661x10^-24g is achieved and is 20.085294g (the answer i got before i divided though you'd include1.661x10^-24g appropriately) the real mass of the carbon atom.
