How many molecules are in 105 g of sugar

(C12H22O11)?
Answer in units of molec

mols sugar = grams/molar mass = ?

Then 1 mol of anything contains 6.02E23 molecules.

To calculate the number of molecules in 105 g of sugar (C12H22O11), we need to use the concept of Avogadro's number and the molar mass of sugar.

1. Start by obtaining the molar mass of sugar (C12H22O11).
The molar mass can be calculated by adding up the atomic masses of all the atoms in the chemical formula.

C (Carbon) atomic mass = 12.01 g/mol
H (Hydrogen) atomic mass = 1.008 g/mol
O (Oxygen) atomic mass = 16.00 g/mol

To get the molar mass of sugar:
12 (number of carbon atoms) x 12.01 g/mol (carbon atomic mass) +
22 (number of hydrogen atoms) x 1.008 g/mol (hydrogen atomic mass) +
11 (number of oxygen atoms) x 16.00 g/mol (oxygen atomic mass)

Molar mass of C12H22O11 = (12 x 12.01) + (22 x 1.008) + (11 x 16.00) g/mol

2. Calculate the moles of sugar.
Moles = mass / molar mass

Given that the mass is 105 g, substitute the values:
Moles of sugar = 105 g / molar mass of C12H22O11

3. Use Avogadro's number to convert from moles to molecules.
1 mole of any substance contains 6.022 x 10^23 molecules (Avogadro's number).

Using the number of moles calculated in step 2, multiply it by Avogadro's number to get the number of molecules:

Number of molecules = Moles of sugar x Avogadro's number

By following these steps, you will be able to determine the number of molecules in 105 g of sugar (C12H22O11).
