350 g. Grams is simply a unit of mass.
A similar question would be- i have a piece of string that is 2 inches long. What is its length?
"centi" is 100. 1 centigram is 100 grams, so Denise's sample is 68,400 centigrams. 68400 - 29510 = 38890 centigrams or 388.90 grams.
density = mass/volume → The density of the rock is the mass of the rock divided by the difference in the volume from before the rock was dropped in and afterwards. Its units are grams/ml
you would use mass
It all depends what the substance is. If it's 28 grams of air, the volume is large. If it's 28 grams of rock or lead, the volume is much smaller.
16g x (1/4)mL/g = 4mL
You use a triple-beam scale to measure mass.
Use grams as the base unit and depending on the size of the rock, grams or deckagrams for a pebble, a small rock hectograms for a rock, and kilograms for a little bigger rock (but still small). The point is to use grams as your base unit.
Spring balance. add.Have a crack at the Schiehallion experiment designed to determine the mass of the Earth. Schei ... is a small hill in Scotland.
That all depends on what substance you're handling.5 grams of air have a large volume (many cc).5 grams of water have a smaller volume (fewer cc).5 grams of granite rock have a tiny volume (only one or two cc)
3 grams /cm3
6.705909598079999e+27 grams
Density simply means mass per unit of volume. So, 120 grams divided by 25 cc = 4.8 grams / cc (density).
you simply multiply the two numbers. 1800 cubic centimeters
density = mass/volume = 350/150 = 2.33 grams/cubic centimeter
if the rock is as you say then you could turn it into 3cm cubed and a mass of 30 grams. that means that it is 1cm cubed and a mass of 10 grams, so that means the density is 10 g/cc,while water's is 1 g/cc , finally the rock is ten times heavier then the water.
A measuring jug is all you need for the volume and a mass balance is needed to determine mass.
