Calculate the number of carbon atoms in 1.50g of c6h12o6

Number of C-atoms =  3.01 *10^22

Explanation:

Step 1: Data given

Mass of glucose = 1.50 grams

Molar mass of Glucose = 180.156 g/mol

Molar mass of carbon = 12.01 g/mol

Step 2: Calculate number of moles glucose

Number of moles glucose = mass glucose / molar mass glucose

Moles glucose = 1.50 grams / 180.156 g/mol

Moles glucose = 0.00833 moles

Step 3: Calculate formula units of glucose

0.00833 moles glucose * 6.02 *10^23 = 5.01 *10^21

Step 4: Calculate number of carbon atoms

Glucose has 6 C'atoms in it's molecular formule

Number of C-atoms = 5.01 *10^21 * 6 = 3.01 *10^22

the atomic mass is the bottom number on the element.
