(b) How many C atoms are in 2 mol of sucrose? Molecular formula of sucrose is , each sucrose molecule contains 12 carbon atoms.

## How many atoms are there in 1 mole of sucrose?

Hint: The molecular formula of sucrose is (C12H22O11). We can clearly see that sucrose contains 12 moles of carbon atoms, 22 moles of hydrogen atoms and 11 moles of oxygen atoms. 1 mole sucrose is the same as 1 mole of sucrose atoms.

## How many carbon atoms are in a mole of sugar?

Example: The molecular weight of the sugar molecule found in cane sugar is the sum of the atomic weights of the 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms in a C12H22O11 molecule. C12H22O11 has a molecular weight of 342.299 amu. A mole of C12H22O11 would have a mass of 342.299 grams.

## How many atoms are in 2.00 moles carbon?

In one mole of carbon, there are 6.02×1023 atoms. So in two moles, there will be twice that: 1.204×1024 .

## How many moles of carbon are in one mole of sucrose?

So, 1 mole of sucrose contains 12 moles of carbon atoms, 22 moles of hydrogen atoms, and 11 moles of oxygen atoms.

## How many grams of carbon are in 100.0 g of sucrose show your work?

A more complex example is sucrose (table sugar), which is 42.11% carbon, 6.48% hydrogen, and 51.41% oxygen by mass. This means that 100.00 g of sucrose always contains 42.11 g of carbon, 6.48 g of hydrogen, and 51.41 g of oxygen.

## How many atoms are there in a mole of Ca Oh 2?

Each atom of Ca(OH)2 has6.02×1023atoms per mole. So, the element of Ca(OH)2 will have, 6.02×1023atoms per mole. Therefore, a mole of Ca(OH)2 has 5×6.02×1023 atoms.

## How many atoms does C5H12?

Pentane is an organic compound with the formula C5H12—that is, an alkane with five carbon atoms.

## How many atoms are in h202?

Hydrogen Peroxide

Two hydrogen atoms can also bond with two oxygen (O) atoms (peroxide), making the formula H2O2.

## How many atoms of oxygen are present?

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

## Is Avogadro’s Number?

Avogadro’s number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×1023 mol-1 and is expressed as the symbol NA. Avogadro’s number is a similar concept to that of a dozen or a gross.
