What is the atomic weight of propane?
Propane doesn't have an, atomic number. Atomic numbers are reserved for elements. It is a alkane molecule with 3 Carbons and 8 Hydrogens (C3H8). H H H | | | H--C---C---C--H | | | H H H
What is the atomic mass of glucose?
Well, the formula is C6 H12 O6. So that means there are 6 carbons, 12 Hydrogens, and 6 oxygens.A carbon atom is about 12 amu.A Hydrogen atom is about 1 amu.An oxygen atom is about 16 amu.So therefore,6carbons(12 amu each) + 12 Hydrogens(1 amu each) + 6 oxygens(16 amu each)=72 + 12 + 96 =180 a.m.u
Does one mole of water contain half mole of oxygen atoms?
Well, 1 molecule of water is made up of 2 hydrogens and 1 oxygen. And it is not possible to have 1/2 a molecule of water, therefore, you have to have at least 1 complete oxygen in there, not 1/2.
What is the molar mass of C7H16?
'Exact' Mol mass of heptane, C7H16, (in 4 and 9 significant decimals):100.125200512 g mol−1
How is the mass of a single particle changed to get the mass of one mole of particles?
To convert the mass of a single particle to the mass of one mole of particles, you multiply the mass of the individual particle by Avogadro's number, which is approximately (6.022 \times 10^{23}) particles per mole. This calculation provides the total mass of one mole of that specific particle. For example, if a single particle has a mass of (m) grams, the mass of one mole would be (m \times 6.022 \times 10^{23}) grams.
What is the molecular weight of propane?
Propane is a molecule consisting of 3 carbons and 8 hydrogens, and is written in the form of C3H8. Carbon has a molecular weight of 12, and hydrogen of 1. Therefore. 3 carbons x 12 = 36 8 hydrogens x 1 = 8 36+8 equals 44
What happens to the bonds between atoms in a substance that undergoes a chemical reaction?
At least one electron from one of the atoms is transferred from an orbital where it occurs in a single atom to either an orbital in one of the other atoms, forming an ionic bond between the two atoms, or to a different orbital that can exist only under the influence of two atoms, forming a covalent bond between the two atoms. In the latter instance, but not the former, the atoms bonded can be atoms of the same element.

What is the method to calculate the bond energy per mole for forming all the bonds of carbon dioxide (CO2)?
To calculate the bond energy per mole for forming all the bonds of carbon dioxide (CO2), you would add up the bond energies of the individual bonds in the molecule. The bond energy is the energy required to break a bond. In the case of CO2, you would calculate the bond energy for the two carbon-oxygen double bonds and add it to the bond energy for the carbon-oxygen single bond. This total energy would then be divided by the number of moles of CO2 to get the bond energy per mole.
Does one mole of water contain half mole of oxygen atoms?

What are some physical properties used to organize the periodic table?
The historically popular chart to which you refer is partially organized by the amount of carbons present in the mole. ;P
Does One mole of water contains half mole of oxygen atoms?
Well, 1 molecule of water is made up of 2 hydrogens and 1 oxygen. And it is not possible to have 1/2 a molecule of water, therefore, you have to have at least 1 complete oxygen in there, not 1/2.
How many grams are there in 0.61 mol of C6H12?
First calculate how many grams a mole of C6H12 weighs: Hydrogen is 1, and you have 12 hydrogens. Carbon is 6 and you have 6 carbons. So a mole weighs 1x12 + 6x6 = 48. Now multiply 48 x .61 and you have it. Final answer is in grams
How many atoms of 5.60 moles of C2H6?
Okay, 1 mole of any substance contains 6.02x1023 representative particles. So, if you have a mole of C2H6 (ethane), you have Avogadro's number of molecules. You're asking about atoms, so if you look at the formula for ethane, you see 2 carbons and 6 hydrogens for a total of 8 atoms per molecule. Multiply Avogadro by 8 to get the total number of atoms. Then multiply by the given number of moles.6.02x1023 x 8 (#of atoms) x 5.6 (number of moles) = 269.7x1023 = approximately 2.7x1025 atoms.
What is the molecular formula of a compound with an empirical formula of C4H9 and a gram formula mass of 114 grams mole?
To determine the molecular formula from the empirical formula and gram formula mass, first calculate the empirical formula mass of C4H9 (4 carbons + 9 hydrogens). Then, divide the gram formula mass by the empirical formula mass to find the ratio. Finally, multiply the subscripts in the empirical formula by this ratio to get the molecular formula, which in this case is C8H18.
