Carbon 13 has 7 neutrons.The atomic mass represents the total number of protons and electrons. Carbon atoms have 6 protons. Therefore, the atomic mass being 13, it has 7 neutrons.
C14H30 is the formula and 14 carbons are there in kerosene.
Molar mass of CArBON 13 = 105.7758 g/mol
13
Carbon-13 make up 1.1% of carbon atoms. .011 x 19000 carbon atoms = 209 carbon-13 atoms present.
There are multiple types of carbon atoms (Carbon 12, Carbon 13, and Carbon 14).
9.00 grams carbon 13 ( 1 mole C13/13.00355 grams)(6.022 X 1023/1 mole C13) = 4.17 X 1023 atoms of carbon 13 -------------------------------------------
0,666 moles
There are 33 atoms in that molecular formula. C13H18O2 (the molecular formula for Ibuprofen) has 13 carbon atoms, 18 hydrogen atoms, and 2 oxygen atoms.
A diamond is composed of carbon atoms. The atomic number of carbon is 6, so all carbon atoms have 6 protons in their nuclei. The number of neutrons depends on the isotope of carbon. Carbon-11 atoms have 5 neutrons, carbon-12 atoms have 6 neutrons, carbon-13 atoms have 7 neutrons, and carbon-14 atoms have 8 neutrons. Refer to the related links below to see the Wikipedia articles on carbon and diamond.
.385 moles of atoms are in 5.00 of 13c. 5/13 = 0.385 mol
Carbon-12 and carbon-13 are isotopes of carbon (different atoms of the same element with same number of protons but different number of neutrons). Carbon-13 has 7 neutrons while carbon-12 have 6 neutrons. Both have 6 protons and 6 electrons.
Carbon 12 the most common contains 6 Carbon 13 contains 7 Carbon 14 contains 8
28. Acyclic alkanes have the formula CnH(2n+2). If n is 13, 2n+2 is 28.
C13H18O2 = ibuprofen 7.4 X 1025 carbon atoms (1 mole C atoms/6.022 X 1023)(1 mole ibuprofen/13 mole carbon) = 9.5 moles ibuprofen ------------------------------
Carbon 13 has 7 neutrons.The atomic mass represents the total number of protons and electrons. Carbon atoms have 6 protons. Therefore, the atomic mass being 13, it has 7 neutrons.
