How many atoms in c8h18?
There are 8 carbon (C) atoms and 18 hydrogen (H) atoms in C8H18.
What is the molecular formula of CH2 with molar mass about 42 g?
The molar mass of a compound is the sum of the molar masses of its individual atoms. With a molar mass of approximately 42 g, a molecular formula of C2H4 (ethene) fits the criteria, where two carbon atoms (212 g/mol) and four hydrogen atoms (41 g/mol) yield a total molar mass close to 42 g/mol.
How many moles of atoms are there in 75.10 grams of chlorine?
To find the number of moles of atoms in 75.10 grams of chlorine, you need to first determine the molar mass of chlorine. Chlorine has a molar mass of approximately 35.45 g/mol. Next, you can use the formula Moles = Mass / Molar Mass to calculate the moles of chlorine atoms in 75.10 grams. This would result in approximately 2.12 moles of chlorine atoms.
How many atoms of carbon are in 2.50 grams of theobromine C7H8N4O2?
To calculate the number of carbon atoms in 2.50 grams of theobromine (C7H8N4O2), you first need to find the molar mass of theobromine. The molar mass of theobromine is 180.16 g/mol. From the molecular formula, there are 7 carbon atoms in one molecule of theobromine. Therefore, using the molar mass and the number of carbon atoms in the molecule, you can calculate the number of carbon atoms in 2.50 grams.
What is the mass in g of 9.44x10 23 atoms of lithium?
To calculate the mass of 9.44x10^23 atoms of lithium, you can use the molar mass of lithium, which is approximately 6.94 g/mol. Divide the number of atoms by Avogadro's number to get the number of moles, then multiply by the molar mass to get the mass in grams.
How many atoms of the element makes up molar mass?
The molar mass is the sum of the atomic weights of atoms contained in the molecule.
What is a molar mass and what is it used for?
The molar mass is the sum of atomic weight of the atoms contained in a molecule. Example: water, H2O The molar mass is: 2 x 1,008 + 15,999 = 18,015 Molar mass is used in many calculus in chemistry.
How do you find the molar mass of an elemnt?
Molar mass is a term applied for molecules, not for atoms.
What do you mean by molar mass of an element?
Molar mass is defined as the mass of 6.022x1023 atoms/molecules of a given substance.
What is the molar mass of oxygen gas?
Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.
What is the molar mass of S2Cl2?
The molar mass of S2Cl2, which consists of two sulfur atoms and two chlorine atoms, can be calculated by summing the atomic masses of these elements. The molar mass of S2Cl2 is approximately 135.04 g/mol.
How do you find the molar mass of an atom?
To find the molar mass of an atom, you need to add up the atomic masses of all the atoms in its chemical formula. This can be determined from the periodic table. The unit for molar mass is grams per mole.
Does the molar mass of a compound change depending on the weight of the compound?
Molar mass depend on the ,mass,type and number of atoms in molecules of compound.
How many atoms in c8h18?
There are 8 carbon (C) atoms and 18 hydrogen (H) atoms in C8H18.

The mass of a sample of nickelaverage atomic mass 58.69 amu is 11.74g how many atoms does it contain?
To find the number of atoms in the sample, we need to first calculate the number of moles of nickel present in the sample using its molar mass. The molar mass of nickel is 58.69 g/mol. Dividing the mass of the sample by the molar mass gives us 0.200 moles of nickel. Finally, multiplying this by Avogadro's number (6.022 x 10^23 atoms/mol) gives us approximately 1.20 x 10^23 atoms in the sample.
