What is the SI unit for the amount of a substance that contains as many particles as there are atoms in exactly 12 grams of carbon -12?
mole
How many grams do 3.61020 atoms of silicon weigh?
Each mole of particles have 6.02 x 10^23 particles. (3.6 x 10^20) / (6.02 x 10^23) = 0.000598 mol of Silicon Ar of Si (Silicon) = 28.1g/mol mass = number of moles x Ar mass = 0.000598 mol x 28.1g/mol = 0.0168g of silicon
How many moles of silicon are in 245 g of silicon?
1 mole Si = 28.0855g Si 245g Si x 1mol Si/28.0855g Si = 8.72 moles Si
What is the mass of 42.6 mol of Si?
Well, isn't that a happy little question! To find the mass of 42.6 moles of silicon, you'll need to multiply the number of moles by the molar mass of silicon. The molar mass of silicon is approximately 28.0855 grams per mole, so when you multiply that by 42.6 moles, you get a mass of about 1197.6 grams. Just like painting a beautiful landscape, it's all about following the right steps with a touch of joy and curiosity!
What is the unit for mole in calculations?
The mole is an SI unit. It is the SI unit for the amount of matter in a substance.In fact, it is an SI base unit, meaning it is defined by measurements in a laboratory and not in terms of other units.One mole of a substance is the number of entities or elementary particles in that substance equal to the number of atoms in exactly 12 g of the carbon-12 isotope.
How many atoms are there in 6.26 g Si?
.250 mole 7.02 ------ 28.09 = .250
How many moles dose 11 grams of silicon contain?
11 g x 1 mol Si/28.0855 g Si= 0.39 mol Si 205g He x 1mol He/4.002602 g He=51.2 mol He
What is the si unit for amount of substance?
The SI unit for amount of substance is the mole, symbolized as "mol." It is used to measure the quantity of chemical entities, such as atoms, molecules, or ions, in a sample.

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 many atoms of Si are in H4SiO4?
In a molecule of H4SiO4 only one Si atom is present
How many atoms of Si are in 237 g of Si?
237g / 28 gmol-1 = 8.46mol. 8.46 x (6.02x1023) = 5.09x1024 silicon atoms.
How many grams of silicon would there be in a sample that contained 9.991052 atoms?
1 mol of Si contains 6.02 x 1023 atoms (avogadro constant). Amount of Si = (9.99x1052) / (6.02x1023) = 3.75mol Molecular mass of Si is 28.1. Mass of Si = 3.75 x 28.1 = 105g
