Question

How many atoms are in 56 grams of silicon?

Answer 1

`atoms=1.2x10^(24)atomsSi`

Step-by-step explanation:

Hello there!

In this case, by considering the mass-mole-particles relationships, it is possible to compute the atoms of silicon by firstly computing the moles via its atomic mass (28.1 g/mol):

`mol=56gSi*(1molSi)/(28.1gSi) =2.0molSi`

Next, via the Avogadro's number, we can compute the atoms of silicon:

`atoms=2.0gSi*(6.022x10^(23)atomsSi)/(1molSi)\\\\atoms=1.2x10^(24)atomsSi`

Best regards!
