What is the density of a substance that has a mass of 54 grams and a volume of 3centimeters to the 3rd power?
This is simple math. Density=Mass(grams)/Volume(milliliters) so since 3^3=27 then it works out to a simple D=54/27 aka 2. 2kg/L to be exact.
How many copper atoms are in a pure copper statue with a mass of 129 kg?
The atomic weight of copper is 63.546 grams per mole. 129 kg is equal to 129000 grams. So there are 2030.03 moles of copper. There are 6.022 x 10^23 copper atoms in a mole. So there are 12.22 x 10^26 atoms.
How many milligrams are there in 27 grams?
There are 1000 milligrams in one gram. Therefore, 27 grams is equal to 27 x 1000 = 27000 milligrams.
What is 27 rounded to the nearest whole gram?
It is 27 grams.
What is the approximate density of the cube if each side was 3cm and the mass is 12g?
Density = mas/volume = 12 g/27 cc = 0.44... recurring grams per cubic centimetre.
What is the density of a block of aluminum that has mass 27 grams of and a volume 10 cubic cm?
The density is the mass per unit volume. So, the density = 27/10 = 2.7 grams/cc
The Earth has a radius of 4000 miles.One cubic meter of rock has an average mass of 5 metric tons. What is the mass of the Earth in grams?

If 40 grams of sodium hydroxide and 3 grams of hydrogen gas are produced when 27 grams of sodium metal is consumed how many grams of liquid water must have been added?
27 g Na + H2O = 40 g NaOH + 3 g H2. Law of Conservation of Mass. The reactants must have the same number of grams of the products. 40 + 3 = 43. 43 - 27 = 16 g H2O.
How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles water in 27 grams
Mass of the earth in grams?
Go to the Wikipedia, and look up the mass in kilograms. Then multiply that by 1000 to convert to grams. (Since you will find the number in scientific notation, this means adding 3 to the exponent.)

What is the mass in grams of 1.00 mol Al?
7 X 102 g Al this is the awnser using significant figures
A substance has a mass of 27 grams and a volume of 10 cubic centermeter its denstity is what?
Not sure that anything has a volume of a cubic centremeter, since there is no such measure. Cubic centimetre, yes. Density = Mass/Volume = 27 g / 10 cc = 2.7 grams per centimetre.
What is the density of a liquid that has a volume of 1000 ml and a mass of 27 grams?
2.7 gram per cubic centimeter
