Please help with these two problems!
1. 566g of C12H22O11=______ C atoms
2. 12 molecules chlorine gas= ________ atoms of Cl
Change 566 g to mols.
mols = grams/molar mass
Change mols to # molecules. You know there are 6.02E23 molecules/ 1 mol so
# mols x 6.02E23 = # molecules C12H22O11
Then the formula tells you there are 6 C atoms in 1 molecule so # C atoms must be 12 x the number of molecules.
Sure, I'd be happy to help you with these problems! Let's break them down one by one:
1. To find the number of carbon (C) atoms in 566g of C12H22O11, we need to use the concept of Avogadro's number and molar mass.
Step 1: Find the molar mass of C12H22O11. The molar mass is the sum of the atomic masses of all the atoms in the compound. You can find the atomic masses of carbon (C), hydrogen (H), and oxygen (O) from the periodic table.
The atomic mass of carbon (C) is approximately 12.01 g/mol.
The atomic mass of hydrogen (H) is approximately 1.01 g/mol.
The atomic mass of oxygen (O) is approximately 16.00 g/mol.
Now, multiply the number of carbon atoms (12) by the atomic mass of carbon (12.01 g/mol), the number of hydrogen atoms (22) by the atomic mass of hydrogen (1.01 g/mol), and the number of oxygen atoms (11) by the atomic mass of oxygen (16.00 g/mol). Then sum up the products to obtain the molar mass of C12H22O11.
Step 2: Calculate the number of moles of C12H22O11. This can be done by dividing the given mass (566g) by the molar mass of C12H22O11. This will help us determine the number of moles of C12H22O11 in 566g.
Step 3: Finally, multiply the number of moles of C12H22O11 obtained in Step 2 by Avogadro's number, which is approximately 6.022 x 10^23 molecules/mol. This will give you the number of molecules of C12H22O11.
As there are 12 carbon atoms in one molecule of C12H22O11, the final answer to this problem will be obtained by multiplying the number of molecules of C12H22O11 by 12.
2. To find the number of chlorine (Cl) atoms in 12 molecules of chlorine gas (Cl2), we need to consider the fact that each molecule of chlorine gas contains two chlorine atoms.
Step 1: Multiply the number of molecules of chlorine gas (12) by the number of chlorine atoms per molecule (2) to get the total number of chlorine atoms.
So, the final answer to this problem will be 12 multiplied by 2, which equals 24 atoms of chlorine.
I hope this helps you understand the process of solving these types of problems! Let me know if you have any further questions.
