Will give brainliest! mole calculations! In a sample of 92.8 moles of C3H8 , how many atoms of hydrogen are there? (Express your answer in scientific notation with the correct number of significant digits)
To show scientific notation in your answer, " x1018 " would be typed in as " *10^18 ".

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
