9 atoms = 1 Copper + 2 Nitrogen + 6 Oxygen
density= mass/volume =1800g/200cm3 divide density= 9 g/cm3
The gram atomic mass of sodium is 22.9898. Therefore, 100.0 grams of sodium contains (100.0/22.9898) X (Avogadro's Number) of atoms, or 2.619 X 1024 atoms, to the justified number of significant digits.
If the compound stated in the question exists, its gram molecular mass is (14 times the gram atomic mass of carbon) plus (9 times the gram atomic mass of hydrogen) + (15 times the gram atomic mass of chlorine), or about 709 grams. Therefore, the number of molecules of the compound in 1.0 gram of it is (1.0)(Avogadro's number)/709 or about 8.49 X 1020. Each molecule contains 14 (exact) carbon atoms, for a total of 1.2 X 1022 atoms of carbon, to the justified number of significant digits.
The number of aluminium atoms ia 0,44638973.10e23.
9 kilograms = 9000 grams
The mass is 295 grams. This is multiplication and subtraction. 9 x 238 = 2142 grams for the balls Total - ball mass = box mass 2437 - 2142 = 295 grams
Properly, one measures mass in grams. 9 milliliters of 4 deg. Celsius water has the mass of 9 grams. That mass would be the same on any planet or even in near weightlessness in space.
9000 grams equal 9 kilograms
9 atoms = 1 Copper + 2 Nitrogen + 6 Oxygen
The mass in grams of one fluorine atom is 18.998 grams per mole. Fluorine is a gas that has the atomic number of 9.
If a bar of copper has a mass of 216g and a volume of 24 cm3 then its density is 9 g/cm.
Grams measures mass. Centimeters measures length.
You can just use a set of weigh scales.
I am assuming you're asking how many atoms are in copper nitrate.There are two compounds that could be called copper nitrate copper(I) nitrate, CuNO3 and copper(II) nitrate Cu(NO3)2The working for Cu(NO3)2 is as follows:Cu tells you that there is one copper atom N tells you that there is one nitrogen atom, and O3 tells you that there are three oxygen atoms. That would make five atoms, but the NO3 is in parenthesis with a two after it. That means the NO3 occurs twice. This gives you a total of 9 atoms. Was that the question? This compound also breaks down into ions it gives a total of three ions one copper ion and two NO3 otherwise known as nitrate ions.The same working applied to CuNO3 would give you 5 atomsI have not seen this question phrased in this manner. Often you will be given a mass and asked how much of this compound is in this mass of the substances.
0.9 km does not convert to grams. One is length and the other is mass. .9 kg equals 900 grams.
A mole of any element contains 6.022*1023 (Avogadro's Number) atoms of that element. So a mole of copper would contain 6.022*1023 atoms of copper.
