Question

finding mass?

Answer 1

\[M_{\text{Mg}}=24.3 [\text{g}/{\text {mol}}]\]
\[N_A=6.022\times10^{23} [\text{molecules}/{\text {mol}}]\]

Answer 2

its 10^24 my bad

Answer 3

so you have
\[6.98 × 10^{24}[\text{molecules}]\]

Answer 4

so lets find the number of moles you have

\[\frac{6.98 × 10^{24}[\text{molecules}]}{ 6.022\times10^{23} [\text{molecules}/{\text {mol}}]}=\]

Answer 5

how much?

Answer 6

how many moles is this?

Answer 7

its a bit more than 10 moles

Answer 8

now multiplying by 24 g/mol,

we get almost 300 grams

Answer 9

thank you very much

Answer 10
