Answer: 67.5
Step-by-step explanation:
Given: The mass of drug = 450 mg
The mass percent error = 15%
Which can be written as 0.15.
We use the formula :-
[tex]\text{Error}=\text{Previous value }\times\text{Percent error}[/tex]
Similarly, [tex]\text{Mass Error}=\text{Mass of drug }\times\text{Mass percent error}[/tex]
[tex]\Rightarrow\ \text{Mass Error}=450\times0.15=67.5\ mg[/tex]
Hence, the mass error would be 67.5 mg.
