Question #844e5

Answer 1

`1.2 xx 10^24`

Explanation:

1 mol of `CO_2` = `(12 + 2*16)` g = `44` g

And the Simplest Unitary Method Comes!

44 g of `CO_2 rarr` 1 mol

1 g of `CO_2 rarr` `1/44` mol

88 g of `CO_2 rarr` `88/44` mol = 2 mol

As, 1 mol = `6.022 xx 10^23`,

2 mol = `"2 mol" xx 6.022 xx 10^23 color(white)(l)"molecules/mol"= 12 xx 10^23color(white)(l) "molecules" = 1.2 xx 10^24 color(white)(l)"molecules"`
