You have 10.5 moles of C5H12, how many moles of C do you have?
There are 5 mols C in each mol of C5H12; therefore, in 10.5 mols C5H12 there must be 5*10.5 = ? mols C.
Well, if we have 10.5 moles of C5H12, we need to figure out how many moles of carbon (C) there are in one mole of C5H12. Let me think... Ah, got it! There are 5 carbon atoms in one molecule of C5H12. So, for each mole of C5H12, there are 5 moles of C.
Now, if we have 10.5 moles of C5H12, we can multiply that by 5 to find the moles of carbon. That would give us a grand total of... wait for it... 52.5 moles of C! That's a whole lot of carbon atoms clowning together, isn't it?
To determine the number of moles of carbon (C) in 10.5 moles of C5H12 (pentane), we need to look at the molecular formula of pentane.
The molecular formula of pentane (C5H12) indicates that it contains 5 carbon atoms (C). Therefore, for every 1 mole of pentane, there are 5 moles of carbon.
Since we have 10.5 moles of pentane, we can multiply this value by the ratio of carbon atoms to pentane molecules.
10.5 moles pentane x 5 moles C / 1 mole pentane = 52.5 moles of carbon (C)
So, you have 52.5 moles of carbon (C) in 10.5 moles of pentane (C5H12).
To determine the number of moles of C in 10.5 moles of C5H12, we need to consider the chemical formula of C5H12.
The formula tells us that there are 5 carbon atoms (C) in one molecule of C5H12. Therefore, to calculate the number of moles of C, we multiply the number of moles of C5H12 by the ratio of the number of carbon atoms to the total number of atoms in C5H12.
The total number of carbon atoms in 10.5 moles of C5H12 is 10.5 moles × 5 carbon atoms/mole = 52.5 moles of C.
So, you have 52.5 moles of carbon (C).
