 Question 37460: Answer by Cintchr(481)   (Show Source): You can put this solution on YOUR website!((270.1 - 273.1)(2.191 x 10^-5)) / (6.712 x 10^4) This one I am going to work without going into the fancy formula notation since it seems to not like decimals right now Lets deal with the numerator ... ((270.1 - 273.1)(2.191 x 10^-5)) ((-3 x 10^0)(2.191 x 10^-5)) multiply and add (-3 * 2.191) x (10^0 x 10^-5) (6.573 x 10 ^-5) since the denominator is already a single expression ... divide and subtract (6.573 x 10^-5)/(6.712 x 10^4) (6.573/6.712) x (10^-5 x 10^4) Rounding to 3 places.... (0.979 x 10^-9) since we have to have one digit in front of the decimal place ... 9.79 x 10^-8
