A balance calibration curve (weight vs. force) as shown in the text has a slope of 7.385 and an intercept of 4.029. What weight in grams will the device show when the downward force is 267.1 (arbitrary units)? The balance reads to two decimal places.

Question

Quizplus · Accepted Answer

The equation of the calibration curve is:Force = 7.385 * Weight + 4.029To find the weight when the force is 267.1, we can rearrange the equation to:Weight = (Force - 4.029) / 7.385Plugging in the value of Force, we get:Weight = (267.1 - 4.029) / 7.385 = 35.622 gramsSince the balance reads to two decimal places, the answer is 35.62 grams.
