Homework Answers
2)
1 mole of CCl4 has 6.02*1023 molecule
3.87 mole of CCl4 has (6.02*1023*3.87) molecule
number of molecule of CCl4 = 6.02*1023*3.87
number of molecule of CCl4 = 23.3*1023
3)
1 mole of C6H12O6 has 6.02*1023 molecule
2.5 mole of C6H12O6 has (6.02*1023*2.5) molecule
number of molecule of C6H12O6 = 6.02*1023*2.5
number of molecule of C6H12O6 = 15.1*1023
1 molecule of C6H12O6 has 6 O atom
15.1*1023 molecule of C6H12O6 has (6*15.1*1023) O atom
number of O atom = 6*15.1*1023
number of O atom = 90.6*1023

calculations for mole ratio on KCLO3, KCL, and O2 and
explanation on how to do it so I can better understand. please and
thank you.
I thought you can only do mole ration if you have an equation and
after you balance. I'm so confused.
