Answer:
Explanation:
This is an example of back titration.
You add a known excess of HCl to the CaCO₃. Some of it reacts with the CaCO₃.
You titrate the left-over HCl.
From the difference you can calculate the amount of CaCO₃.
100.09
CaCO₃ + 2HCl ⟶ CaCl₂ + H₂CO₃
m/g: 1.2450
V/mL: 65.00
c/mol·L⁻¹: 0.4984
NaOH + HCl ⟶ NaCl + H₂O
V/mL: 37.15
c/mol·L⁻¹: 0.2065
1. Total moles of HCl
2. Excess moles of HCl
3. Moles of HCl that reacted
n = (32.40 - 7.671) mmol HCl = 24.72 mmol HCl
4. Moles of CaCO₃
5. Mass of Ca

This is a monounsaturated fatty acid .
Saturated fatty acids are those where all the C atoms are bonded by single bonds.
When they are bonded by single bonds, each C has the maximum amount of H atoms it can bond to. It’s then saturated with H atoms.
When there are fatty acids with double bonds, then they are called unsaturated bonds as they don’t have the maximum number of H atoms.
The fatty acid in the question all the C atoms are bonded by single bonds except for one double bond , therefore it’s monounsaturated fatty acid
