To find the amount of moles in 0.00032g of lithium, all you have to do is apply the formula n (moles) = m (mass, grams)/MM(molar mass). Molar mass is the atomic weight of the substance, and all you have to do is look at the periodic table. Lithium's is 6.94.
So, n (lithium) = 0.00032/6.94
n (lithium) = 0.000046 moles (2 d.p)
Take into account the number of atoms in the molecule for other calculations. Some elements are diatomic, which means they occur as two atoms of the same element bonded, such as hydrogen (H2) and chloride (Cl2). This means that to find moles of a substance such as Cl2, you need to multiply the molar mass by 2, since there are 2 atoms. Additionally, for compounds, you need to find the sum of all the elements involved's molar mass. For example, when you’re trying to find the moles in table salt, NaCl (sodium chloride), add the atomic weight of sodium and chlorine together for your molar mass.

Answer:
Figure 1
Explanation:
In this case, we have to ester with a <u>"malonic synthesis"</u> in which we have to add a strong (ethoxide) to produce an enolate ion that would form a new C-C bond with an alkyl halide (ethyl bromide and bromo pentane). Then a <u>"nucleophilic acyl substitution reaction"</u> takes place to add thiourea, in this step two ethanol groups are eliminated to form a cyclic structure. Finally, an "<u>elimination reaction"</u> happen by the addition of sodium hydroxide generating a double bond and a negative charge in the sulfur atom that is neutralized with the positive charge of sodium.
See figure 1 for the total mechanism

In order to get all the amino acids that the body needs to produce proteins, one must eat and drink the necessary food containing amino acids. Amino acids are what comprises proteins thus, in order to obtain the average amount of amino acid, make sure that you have an enough intake of foods rich in proteins.
