What is used to measure the number of representative particles in the substance?
mole
Is 1 mole of particles a very large number of particles or a very small number?
1 mole of representative particles of a substance is a very large number. It represents 6.02294x1023 particles.
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.
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 does an Avogadro's number of a substance is called a mole mean?
It is the number of particles in a mole of any substance
How many atoms are in 2.8 moles o silicon?
One mole of any substance contains Avogadro's number of representative particles. Avogadro's number is 6.02x1023. So, if you have 2.8 moles of something, you multiply that number by Avogadro to get 1.69x1024.
The si base unit used to measure the amount of a substance whose number of particles is the same as the number of atoms of carbon in exactly 12 g of carbon-12?
Mole
What are the molar conversions between moles and representative particles?
avagadros number
How is temperature differ from thermal energy?
Thermal Energy is theTOTAL Ek of atoms in a substance.Temperature is the measure of the AVERAGE Ek of the atoms in a substance.Thermal energy: The total amount of kinetic energy contained in all the particles of a substance. The greater the kinetic energy of the particles in the substance, the more thermal energy the substance has. But thermal energy also depends on the number of particles in a substance. The more particles a substance contains, the greater its thermal energy.Temperature vs. Heat :When you think of temperature, you probably think "hot" or "cold." To scientists, temperature is a measure of the average kinetic energy of the particles in a substance. The more kinetic energy the particles have, the higher the temperature of the substance. Unlike thermal energy, however, temperature is not affected by the number of particles the substance contains.(Taken from: Sciencesaurus A Student Handbook Pp. 301-302)
How many representative particles are in 1.45 g of a molecular compound with a molar mass of 237g?
There are 1,45/237 = 0,00612 moles of the compound. Multiplying this amount of substance with Avogadro's number gives us the number of residing molecules: 0,00612 x 6,022*1023 = 3,68*1021 particles.
What are the two things that the thermal energy depends on?
- How fast the particles are moving - The number of particles in a substance
