Question

the amino acid serine has the molecular formula c₃h₇no₃, and the amino acid glutamic acid has the molecular formula c₅h₉no₄. determine how many moles of glutamic acid contain the same number of atoms as 1.30 mol of serine. use the references to access important values if needed for this question. 3 item attempts remaining. moles

Explanation:

Step1: Calculate atoms in 1.30 mol of serine

The molecular formula of serine is $C_3H_7NO_3$. One - mole of serine contains $(3 + 7+1 + 3)=14$ moles of atoms. So, 1.30 mol of serine contains $1.30\times14 = 18.2$ moles of atoms.

Step2: Calculate moles of glutamic acid

The molecular formula of glutamic acid is $C_5H_9NO_4$. One - mole of glutamic acid contains $(5 + 9+1 + 4)=19$ moles of atoms. Let the number of moles of glutamic acid be $n$. Since the number of atoms in glutamic acid is the same as in 1.30 mol of serine, we have $19n=18.2$. Solving for $n$, we get $n=\frac{18.2}{19}=0.958$ mol.

Answer:

0.958
