a graduated cylinder weights 64.376g empty.when i measure 30.0mL into it weights 89.98g.what is the density of the liquid?

64.376g-89.98g=25.604g

then i

25.604/30.0=.853

Two errors, some would consider them major and some minor.

You should subtract the large number from the small number; i.e., 89.98-64.376 = 25.604. As it is, the way you subtracted the value is -25.604. Another question: I wonder why you only weighed the container with water to the same number of places you weighed the empty container?

Second, the value you have for density is right IF you include the units. The answer is 0.853 g/mL.

I made a typo in this part. The corrected part is in bold.

You should subtract the large number from the small number; i.e., 89.98-64.376 = 25.604. As it is, the way you subtracted the value is -25.604. Another question: I wonder why you **DIDN'T WEIGH** the container with water to the same number of places you weighed the empty container?
