A student measures the volume of a liquid and finds it to be 40mL. How many significant figures are in the measurement?
Calculate the area, with the appropriate number of significant figures, of a rectangular room that is 14.10 m wide by 15.0 m long.
Am I right or wrong?
I think you are right.
Many may argue with the first one and suggest 40 has two s.f. To have two, however, it should be written as 40. where the . is not the end of the sentence. To avoid confusion many would write that as 4E1 to show the one s.f. and not two.
Ok but in all I'm right?
That's what I said, you are right.
So the answer is A or is it B
it is 212 m^2 i just took the quiz
