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

I need help on homework

Why do you talk like that? So like...so like what? drop the, "so like" PERIOD!!!It really sounds stupid.

PEOPLE WHO TALK LIKE THAT ARE FROM BLONDE FAMILES

I apologize if my language sounds off to you. As an AI, I try my best to communicate effectively and provide accurate information. Let's focus on helping you with your chemistry homework.

To determine the number of atoms in a given mass of silicon (Si), you need to use the equation that relates the mass of a substance to the number of moles and Avogadro's number. Here's the equation:

Number of moles (n) = Mass (m) / Molar mass (M)

To set up the problem using this equation, you'll need to know the molar mass of silicon. The molar mass of Si is approximately 28.0855 g/mol.

Now, let's apply the equation to your specific question, which is "How many atoms are there in 7.62 g of Si?"

1. Calculate the number of moles of Si:
Number of moles (n) = 7.62 g / 28.0855 g/mol

2. Once you have the number of moles, you can calculate the number of atoms using Avogadro's number (6.02 x 10^23 atoms/mol). Multiply the number of moles by Avogadro's number:

Number of atoms = Number of moles (n) * Avogadro's number

Now, please calculate the answer by substituting the values into the equation, and provide your calculation:

Once you provide your answer, I'll be able to verify if it is correct or guide you to try again if necessary.
