Determining the Number of Moles of Carbon in Threonine
How can we determine the number of moles of carbon in 19.47 g of threonine?
Threonine is an amino acid with the formula C4H9NO3. Let's find out the number of moles of carbon in the given mass.
Answer:
There are approximately 0.1632 moles of carbon in 19.47 g of threonine.
Threonine is an essential amino acid used in creating proteins in our bodies. To determine the number of moles of carbon in 19.47 g of threonine, we need to calculate the molar mass of threonine and then use it to find the number of moles of carbon present.
The molar mass of threonine (C4H9NO3) can be calculated by adding the atomic masses of all the elements present:
Molar mass of threonine = (4 x atomic mass of carbon) + (9 x atomic mass of hydrogen) + (1 x atomic mass of nitrogen) + (3 x atomic mass of oxygen)
Molar mass of threonine = (4 x 12.01 g/mol) + (9 x 1.01 g/mol) + (1 x 14.01 g/mol) + (3 x 16.00 g/mol)
Molar mass of threonine = 119.12 g/mol
To find the number of moles of carbon in 19.47 g of threonine, we use the formula:
Moles of carbon = (Given mass) / (Molar mass)
Moles of carbon = (19.47 g) / (119.12 g/mol)
Moles of carbon ≈ 0.1632 mol
Therefore, there are approximately 0.1632 moles of carbon in 19.47 g of threonine. This calculation helps us understand the composition of threonine and its carbon content.
