To find atoms in number of moles you multiply by avogadra's number (6.022x10^23) then multiply by the number of atoms, in this case it is one because carbon is a monotomic element. The answer is 9.03x10^23 atoms C
Pure diesel does not contain any sulfur atoms. The molecular statement for Diesel is C12H23, which means each molecule of diesel contains 12 Carbon atoms and 23 Hydrogen atoms. Sulfur shows up in diesel because it is in the crude oil originally and the cost of refining out all the sulfur from the diesel is very expensive.
There are a total of 15 atoms in NH4HCO3: 2 nitrogen atoms, 6 hydrogen atoms, 1 carbon atom, and 6 oxygen atoms.
There are 16 atoms in 3CH4, which consists of 3 molecules of methane (CH4). Each methane molecule contains 5 atoms - one carbon atom and four hydrogen atoms. So, 3 molecules of CH4 contain a total of 3 carbon atoms and 12 hydrogen atoms, giving a total of 16 atoms.

In an alkane the number of hydrogen atoms is two greater than twice the number of carbon atoms. If we reverse this rule, we find that the number of carbon atoms is one less than half the number of hydrogen atoms. 32/2=16 16-1=15 So our alkane would have 15 carbon atoms. This alkane would be pentadecane or one of its isomers.
4.5*10^23
Approx. 9.1024 atoms.
The answer is 15 carbon atoms.
One billion equals 109. A mole of magnesium contains Avogadro's number of magnesium atoms. Therefore a billion atoms constitutes 109/(6.022 X 1023) or about 1.66 X 10-15 mole.
9.3*10^15 atoms nickel = ? grams take the number of atoms, divide by one mole and then times by the molar mass of nickel 9.3*10^15atoms /6.02*10^23 atom/mol * 58.69 g/mol =9.1*10^-7 grams
If the compound stated in the question exists, its gram molecular mass is (14 times the gram atomic mass of carbon) plus (9 times the gram atomic mass of hydrogen) + (15 times the gram atomic mass of chlorine), or about 709 grams. Therefore, the number of molecules of the compound in 1.0 gram of it is (1.0)(Avogadro's number)/709 or about 8.49 X 1020. Each molecule contains 14 (exact) carbon atoms, for a total of 1.2 X 1022 atoms of carbon, to the justified number of significant digits.
Ribulose bisphosphate (RuBP) has 15 carbon atoms. It is a 5-carbon sugar molecule that is attached to two phosphate groups.
To calculate the number of atoms in 3 moles of potassium nitrate (KNO3), you use Avogadro's number, which is 6.022 x 10^23 atoms/mol. First, calculate the molar mass of KNO3 (101.1 g/mol) then multiply that by 3 to get the total mass in grams. Next, divide the total mass by the molar mass to get the number of moles, and finally multiply the number of moles by Avogadro's number to get the number of atoms. For 3 moles of KNO3, there are approximately 5.4 x 10^24 atoms.
In one (1) molecule CO2 there are 3 atoms ( 1 C-atom and 2 O-atoms), so in 5 molecules CO2 (5CO2) there are 5 x 3 (= 15) atoms. Thus fifteenis the answer to you.
To calculate the total number of atoms in 15 g of CaH2, we first need to find the number of moles of CaH2 using its molar mass. The molar mass of CaH2 is 42.08 g/mol. Therefore, 15 g of CaH2 is equal to 15/42.08 = 0.356 moles of CaH2. Since each mole of CaH2 contains 3 atoms (1 calcium atom and 2 hydrogen atoms), there are 0.356 * 3 = 1.068 moles of atoms in 15 g of CaH2. This is equivalent to 1.068 * 6.022 x 10^23 = 6.44 x 10^23 atoms.
