- in case cesium-129 is what you were referring to.
Cesium has atomic number as seen on a modern periodic table. A cesium atom nucleus would thus contain an equal number of protons; in addition to that, a <em>neutral</em> atom of cesium would contain the same number of electrons in its electron cloud.
For a particular isotope,
.
This isotope of cesium has a mass number of and contains
protons in each atomic nucleus. One cesium nuclei would therefore contain
neutrons.
Answer:
Density = 0.0007667 Kg/cm³
Explanation:
Given the following data;
Mass of empty beaker = 0.50 kg
Volume of solution = 300 cm³
Mass of glass+solution = 730 g
To find the density of the solution in the glass;
First of all, we would convert the value in grams to kilograms.
Conversion:
1000 grams = 1 kg
730 = X kg
Cross-multiplying, we have;
X = 730/1000 = 0.73 kg
Next, we would determine the mass of the solution.
Mass of solution = Mass of glass+solution - Mass of empty beaker
Mass of solution = 0.73 - 0.50
Mass of solution = 0.23 kg
Lastly, we would solve for the density of the solution;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the formula;
Substituting into the formula, we have;
Density = 0.0007667 Kg/cm³
