What is the volume of 30 g of sodium?
The density of sodium at room temperature is 0.968g/cm3. Density = mass/volume. To find the volume of a substance from its density and mass, divide the mass by the density. V = M/D = 30g/0.968g/cm3 = 31cm3
What part of the atom accounts for most volume?
the nucleus ^^to whoever wrote this answer.. you are stupid. the nucleus is where most of the MASS is contained. so the correct answer is that the volume is found around the nucleus NOT the nucleus... to the above who said he was stupid, you are stupid.
What is the ppm of sodium sulphide?
The ppm (parts per million) of sodium sulphide would depend on the concentration of sodium sulphide in the solution. To calculate the ppm, you would need to know the mass of sodium sulphide dissolved in a known volume of solution. This would allow you to determine the amount of sodium sulphide in relation to the total volume of the solution.
What part of the atom occupies all the volume?
Almost all of the volume of an atom is the space between the nucleus and the electrons.
What are some characteristic properties of elements?
Atomic number: Each element has a unique number of protons in its nucleus, known as the atomic number. Atomic mass: The sum of the protons and neutrons in an atom's nucleus determines its atomic mass. Electron configuration: Elements have a specific arrangement of electrons in their atomic shells, which influences their chemical properties. Valence electrons: The outermost electrons of an atom, known as valence electrons, determine how elements interact with other atoms to form compounds.
Why is sodium metal lighter than iron?
Because it has a fourth shell which means it's valence electrons are further from the nucleus (protons) meaning that there is less attraction between it's electrons and protons; this obviously forms a weaker bond. Sodium has only 3 shells which means its valence electrons are closer to the nucleus.
What is the method to find the average energy (eavg) of the electrons in sodium at absolute zero?
To find the average energy of electrons in sodium at absolute zero, you can use the formula for the Fermi energy, which is given by E (3/5) (h2 / (8 m V(2/3))), where h is Planck's constant, m is the mass of an electron, and V is the volume of the material. By plugging in the values for sodium, you can calculate the average energy of the electrons at absolute zero.
What is the volume of 35.7g of sodium chloride in 100cm3 of cold water?
What is the volume of 35.7g of sodium chloride in 100cm3 of cold water?
What is the volume of 30 g of sodium?
The density of sodium at room temperature is 0.968g/cm3. Density = mass/volume. To find the volume of a substance from its density and mass, divide the mass by the density. V = M/D = 30g/0.968g/cm3 = 31cm3
What is the relationship between the mass and volume of a sodium chloride solution?
Density=Mass/Volume
Does the volume of matter come from protons or electrons?
The number of electron orbitals is where the volume of matter comes from. The more electrons and orbitals, the more volume. The mass comes from the protons and neutrons.
What volume of 5.19M sodium chloride contains 250 moles of sodium chloride?
The answer is 48,17 L.
What is 2 drops of sodium chloride?
This depends on: - the volume of the drop - the concentration of sodium chloride solution
What does 800 milliliters of salt mean?
1. A volume of powdered sodium chloride.2. A volume of water solution of sodium chloride with a non-specified concentration in this case..
What part of the atom accounts for most volume?

How is plasma different?
Plasma is made up of free electrons and atoms that are stripped of their electrons. It has no definite shape or volume. A Solid has a definite shape and a definite volume. A Liquid has no definite shape but has a definite volume. A Gas has no definite shape or volume.
What possible sources of error for the barfoed's test?
Possible sources of error for the Barfoed's test include inadequate mixing of the reagents, inaccurate measurement of the sample volume or reagent volume, contamination of reagents or equipment, incomplete boiling or heating of the test tubes, and improper timing of the reaction.
