Styrofoam is a trade name for polystyrene foam Styrene has an empirical formula of CH It has a molecular mass of 104 amu What is the correct molecular formula for styrene?
The molecular formula for styrene is C8H8. This is derived by multiplying the empirical formula (CH) by a factor of 8 to get the molecular formula. Styrene consists of 8 carbon atoms and 8 hydrogen atoms.
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.
How many moles are present in a sample of 3.2x10 atoms of nickel?
A sample of 3,2x10 atoms of nickel is equal to 0,53.10e-23 moles.
How many moles of silver (Ag) are present in a sample of 3.8 10 to the power of twenty four atoms Ag?
The answer is 6,31 moles Ag.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
How many atoms are present in a 15 mol sample of uranium?
Approx. 9.1024 atoms.
What is the polarity of styrene?
Styrene is nonpolar due to the symmetrical arrangement of its carbon-carbon bonds and the absence of electronegative atoms like fluorine, oxygen, or nitrogen to create dipoles.

How many C-13 atoms are present on average in a 13000-atom sample of carbon?
Carbon-13 make up 1.1% of carbon atoms. .011 x 19000 carbon atoms = 209 carbon-13 atoms present.
Is polystyrene a covalent bond?
Polystyrene is a polymer made of repeating monomer units of styrene, which is a covalent compound. The bonds between the carbon and hydrogen atoms within the styrene monomer are covalent bonds.
Does styrene have a double bond?
Yes, styrene has a double bond between the carbon atoms in its chemical structure, which is part of what makes it a monomer used in the production of polymers like polystyrene.
How do you find out how many atoms are present in calcium?
To find out how many atoms are present in calcium, you would need to use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Simply divide the mass of the calcium sample by the atomic mass of calcium (40.08 g/mol) and then multiply by Avogadro's number to determine the number of atoms present.
If a sample is 10740 years old and has 400 atoms how many atoms are there after the organisms died?
After 10740 years, half of the sample would have decayed, so there would be 200 atoms left. If the original sample had 400 atoms, then there would be 200 atoms left in the sample after 10740 years.
