Question #2af6a

Answer 1

Poorly-worded question!
1. 0.221
2. 1.11

Explanation:

The normal linear description of an analysis is "Desired Quantity = Linear Equation in Analyte". The only way the available option values can come out of the given equation is if 'x' is the desired quantity and 'y' is the analyte. THAT is INCORRECT.

HOWEVER, working it that way we obtain:
`0.82 = 1.75x + 0.433` ; `x = 0.221`

Because the sample was diluted, the original sample must actually be five times this value, or `1.11`
