The subject is chemistry, okay so like The questions states are many atoms are there is 7.62g of Si? But all I am asking is if you can give me the equation to set up th eporblem then ask me to answer it, then I can give you my answer so your can see if it is right, and if it is wrong tell me to try again. Thanks bunch!!!!!!!!
divide the mass of Si by the atomic mass of Si. That give you the number of moles of Si. Now mulitply that number by avagradros number, 6.02*10^23
so basically the answer should be about 1.21 x 10^24
Si
