What else can I help you with?
What is the SI unit used to measure the number of representative particles in a substance?
its the mole.
What is measure of average speed of particles of a substance?
The average speed of particles in a substance is determined by calculating the total distance traveled by all particles over a certain time period, and then dividing by the number of particles. This provides a measure of how fast, on average, the particles are moving within the substance.
Is 1 mole of particles a very large number of particles or a very small number?
A mole of particles is a very large number, equivalent to 6.022 x 10^23 particles. This number is known as Avogadro's number and represents a mole of any substance, whether atoms, molecules, ions, or other particles.
Avogadros number of representative particals is equal to one?
Avogadro's number is the number of particles (atoms, molecules, ions, etc.) in one mole of a substance, which is approximately 6.022 x 10^23. Therefore, 1 mole of any substance contains Avogadro's number of representative particles.
How many moles is 2.17x10 representative particles of bromine?
Since one mole is equal to 6.022x10^23, there are .36 moles in 2.17x10 representative particles of bromine. A mole is a measure used to make atomic calculations for density.
How to calculate number density in a given substance?
To calculate number density in a substance, you divide the number of particles in the substance by the volume of the substance. This gives you the number of particles per unit volume.
What does a mole measure?
An instrument can not be used to measure moles because moles is the amount of grams of a substance divided by the molar mass of the substance. This can not be measured and has to be calculated.
What is the relationship between moles and Avogadro's number in stoichiometry calculations?
In stoichiometry calculations, moles are used to measure the amount of a substance involved in a chemical reaction. Avogadro's number is a constant that represents the number of particles in one mole of a substance. The relationship between moles and Avogadro's number is that one mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 1023. This relationship is important in converting between the mass of a substance and the number of particles present in a reaction.
Does not depend on the number of particles in an object?
Density does not depend on the number of particles in an object, as it is a measure of mass per unit volume. It is an intrinsic property of the material itself, regardless of the amount of substance present.
How many representative particles are in 1.45 g of a molecular compound with a molar mass of 237 g?
1.45 g of a molecular compound with a molar mass of 237 represents 1.45/237 or 6.118 X 10-3 mole. Assuming that "representative particles" in the question means "molecules", this is (6.118 X 10-3){Avogadro's Number} or 3.68 X 1021 molecules.
What does Avogadro's number of representative particles equal to?
one mole.
Avogadros number is the number what?
It is the number of fundamental particles - atoms or molecules - of a substance in 1 mole of that substance.
