Lab insirumenta have a linit of detection ithe smallst amount that can be matesured with reassonsblo precision) Our iptcirephotomaters can retably measure the absorbance of 1.00 mt of a ribeflavin selution with a concentation of 100mgl How many moles of riboftavia would be in thas sample? NOIE For this calculation you need to know that the molar mass of riboflavin is 376.9mol You will also need ts do some unt cohrersions (inL bo L. mig to 9.9 to moles) Because speceophohomery is very shositive, the smallest amount detected will be a very small mumber of moles so express your answer in soientific notation with three significant figures Use the the boxes bebiw to enter your answer. For example, if your answor wece 1.23103, enter 1.23 in the first box and 3 in the stcend box. Be sute to round to thee signiseant fgures as shown in this example moles of rbsflavin =
