Step-by-step explanation:

aWD

Answer 2

`m_(Si)=5.04gSi`

Step-by-step explanation:

Hello,

In this case, we use the Avogadro's number and the atomic mass of silicon to find the grams that are present in that amount of atoms by using the following atoms-mole-mass relationship:

`m_(Si)=1.08x10^(23)atomsSi*(1molSi)/(6.022x10^(23)atomsSi) *(28.1gSi)/(1molSi) \\\\m_(Si)=5.04gSi`

That is why in mole of silicon there are 6.022x10^(23) atoms of silicon as well as 28.1 g of silicon.

Best regards.
