Calculate the mass of a cylindrical cork of diameter 1.00 inches and length 2.50 inches. Pay attention to significant figures, Cork density 0.26 g/ mL

1 answer

there are 2.54 cm in an inch

a cm^3 is the same as a mL

volume = π * .5^2 * 2.5 * 2.54^3
...the result is in cm^3

multiply the volume by the density (.26)...that is the mass in g

round the result to TWO sig fig
...that is the limiting number in the density value
