One group of students recorded the following measurements for their copper cylinder: diameter = 1.266 cm height = 4.978 cm mass = 56.75 g What is the mass density of the cylinder?

A silver sphere with a radius of 5.8 cm weighs the same as a certain aluminum cube. How long are the sides of this cube (in cm)?

Please help. This problem involves finding the radius and volume of a platinum atom using its density. Thank you.

What mass of gasoline (in kg) can be contained in a fuel tank whose dimensions are 45 cm x 83 cm x 23 cm

A rectangular container measuring 18 cm ⨯ 45 cm ⨯ 61 cm is filled with water. What is the mass of this volume of water in kilograms and grams? (Take the density of water to be 1000 kg/m3.)

Why is the average density not a "good" measure of density in this experiment? Mass (kg) Volume(m^3) Density (kg/m^3) 1.16 0.001 1160 2.46 0.0023 1069.565217 5.16 0.005 1032 10.16 0.01 1016 13.66 0.0135 1011.851852         Its a good measure     The average does not account for the human errors in the measurements.     The average does not account for the random errors in the measurements.     The average does not account for the systematic errors in the measurements.

A scanning electron micrograph of xylem vessels in a corn root shows the vessels magnified by a factor of 608. In the micrograph the xylem vessel is 5.60 cm in diameter. What is the diameter of the vessel itself, answer in cm? and By what factor has the cross-sectional area of the vessel been increased in the micrograph?

Blood flows through the aorta at an average speed of v = 18 cm/s. The aorta is roughly cylindrical with a radius r = 17.0 mm. The volume rate of blood flow through the aorta is πr2v. Calculate the volume rate of blood flow through the aorta in L/min.

The laboratory balances have a precision of 0.01g. If you are obtaining the mass of an approximately 5 gram sample, which of the following is a proper way to record this measurement in your laboratory notebook and on your report sheets.     4.92 g     4.92     4.925 g     5.00 g

A group of students wish to determine, experimentally, the bulk density of an unknown material. To determine this amount, the students measured the diameter, height, and mass of various cylinders. These values ​​appear in the table below. Determine: a) The volume of the cylinders that appears in the following table. b) The graph of mass vs. volume.
