A calibration curve for CuSO4 at 635 nm yields a straight line described by the equation y = 2.036 x + 0.722. If the concentration of a sample of CuSO4 is 0.312 M, what is the predicted value of its absorbance? Provide your response to three digits after the decimal.
Homework Answers
Answer
Absorbance = 1.357
Explanation
staight line equation is
y = mx + C
y = 2.036x + 0.722
where,
y = Absorbance
x = Concentration
slope m = 2.036
y intercept C= 0.722
Substituting the value for concentration
y =( 2.036M-1×0.312M) + 0.722
= 1.357
