How many atoms are there in 250 mol Si?
1 mole of anything is 6.022 x 1023 atoms or molecules of that substance. Thus, 2500 atoms of a substance is about 4.151 x 10-21 moles of that substance.

How many atoms of oxygen are in 0.100 moles of silicon dioxide?
There are 2 atoms of oxygen in each molecule of silicon dioxide (SiO2). Therefore, in 0.100 moles of SiO2, there would be 0.100 moles * 2 atoms = 0.200 moles of oxygen atoms. Finally, since 1 mole of any element contains 6.022 x 10^23 atoms, there are (0.200 moles) * (6.022 x 10^23 atoms/mole) = 1.204 x 10^23 atoms of oxygen in 0.100 moles of silicon dioxide.
How many moles are present in gram's of silicon Si?

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.
SI unit for amount?
moles
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.
