In 1.71 gram of sugar (C12H22O11) find the number of. carbon. Atoms added.
To find the number of carbon atoms in 1.71 grams of sugar (C12H22O11), we need to first calculate the molar mass of sugar.
The molar mass of C12H22O11 can be calculated by adding up the atomic masses of carbon (C), hydrogen (H), and oxygen (O):
(12.01 g/mol)(12) + (1.01 g/mol)(22) + (16.00 g/mol)(11) = 342.34 g/mol
Now, we can use the molar mass to determine the number of moles of sugar in 1.71 grams:
1.71 g / 342.34 g/mol = 0.004999 mol
Since there are 12 carbon atoms in one molecule of sugar, to find the number of carbon atoms in 0.004999 mol of sugar, we multiply the number of moles by Avogadro's number (6.022 x 10^23 atoms/mol):
0.004999 mol * (6.022 x 10^23 atoms/mol) = 3.01 x 10^21 carbon atoms
Therefore, in 1.71 grams of sugar, there are 3.01 x 10^21 carbon atoms.
Bot I don't see where you corrected for the 12 C atoms in sucrose.
Apologies for the oversight. Let's correct it.
In each molecule of sugar (C12H22O11), there are 12 carbon atoms (C) present.
To find the number of carbon atoms in 1.71 grams of sugar (C12H22O11), we can use the molar mass and Avogadro's number.
The molar mass of C12H22O11 is calculated as follows:
(12.01 g/mol)(12) + (1.01 g/mol)(22) + (16.00 g/mol)(11) = 342.34 g/mol
Now, we can calculate the number of moles of sugar in 1.71 grams:
1.71 g / 342.34 g/mol = 0.004999 mol
Since each mole of sugar contains 12 carbon atoms, we can multiply the number of moles by the number of carbon atoms per mole:
0.004999 mol * 12 = 0.06 moles of carbon atoms
Finally, using Avogadro's number (6.022 x 10^23 atoms/mol), we can calculate the number of carbon atoms:
0.06 moles * (6.022 x 10^23 atoms/mol) = 3.61 x 10^22 carbon atoms
Therefore, in 1.71 grams of sugar, there are approximately 3.61 x 10^22 carbon atoms.
To find the number of carbon atoms in 1.71 grams of sugar (C12H22O11), you can follow these steps:
1. Determine the molar mass of sugar (C12H22O11). This can be calculated by summing the atomic masses of all the atoms in the molecule. The atomic masses are as follows:
Carbon (C): 12 g/mol
Hydrogen (H): 1 g/mol
Oxygen (O): 16 g/mol
Thus, the molar mass of sugar is:
(12 x 12) + (22 x 1) + (11 x 16) = 144 + 22 + 176 = 342 g/mol
2. Calculate the number of moles of sugar in 1.71 grams. This can be done using the formula:
Number of moles = Mass / Molar mass
Therefore, the number of moles of sugar is:
1.71 g / 342 g/mol = 0.005 moles
3. Use the molar ratio between carbon atoms and sugar molecules to find the number of carbon atoms:
In one molecule of sugar (C12H22O11), there are 12 carbon atoms.
Since there are 0.005 moles of sugar, you can multiply this by the number of carbon atoms per mole to find the total number of carbon atoms:
0.005 moles x 12 carbon atoms/mole = 0.06 carbon atoms
Therefore, there are approximately 0.06 carbon atoms added in 1.71 grams of sugar.
