Is there an SI unit for number of atoms?
No SI unit for no. of atoms. But there is a SI unit to measure the amount of any substance. It is moles and mole is a fixed quantity. Each mole represents a group of 6.022 x 1023 particles. These particles may be atoms or molecules.
What is the formula for osmolarity?
Osmolarity = Molarity x i i = number of particles produced when one formula unit of solute dissolves
How many Cu atoms are present in 85mol?
Since the formula unit of copper is a single atom, the answer is 85 X Avogadro's Number or about 5.119 X 1025.
How many particles does potassium chloride have?
The formula unit of potassium chloride (KCl) has two atoms.
How many moles are present in gallon's of silicon Si?
Gallon is a unit for liquids.
How many mole of silver atoms are 1.8 x 1020 atoms of silver?
Divide 1.8*10^20 (unit: number) particles by 6.02*10^23 (unit: number per mole), Avogadro's number) and you'll get3.0*10^(-4) moles of those particles(In your case particles are atoms, but this is also valid for ANY kind of particles)
What is the unit representing a large number of particles?
Avogadro's number, the mole.
What is a unit representing a large number of particles?
Avogadro's number, the mole.
What shows how many atoms of each element are in a unit of a substance?
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.

What is the mass number of copper?
AMU (Atomic Mass Unit) is the SI masses of particles for nucleus.
What is a unit of substace that contains 6.02x1023 particles 22.4 liters of any gas molar mass in grams?
The Avogadro number of particles is found (by definition) in ONE mole (unit: mol)
What is the SI unit used to measure the number of representative particles in a substance?
its the mole.
Is there an SI unit for number of atoms?
No SI unit for no. of atoms. But there is a SI unit to measure the amount of any substance. It is moles and mole is a fixed quantity. Each mole represents a group of 6.022 x 1023 particles. These particles may be atoms or molecules.
How does increasing the number of particles of a contained gas it's pressure?
Pressure is defined as the force per unit area applied. This force is derived from the collision of particles. Pressure increase when this force is increase, and it applies otherwise too. By increasing the number of particles in a specific amount of gas, there are more particles colliding onto the container. This causes the force per unit exerted by the gas on the container to increase. As such, when one increases the number of particles within a container of gas, the pressure within the container will increase.
Any substance that contains Avogadro's number of particles is called a?
A mole is the unit of measurement based on Avogadro's number. It measures the number of atoms or molecules in a substance.
Which unit is used to represent the chemical quantity of a substance as a number of particles?
The mole (abbreviated mol), which is 6.022 x 1023 particles (atoms, molecules, ions, etc...).
