I'll let you evaluate it...
#"? mol" = 3.16 xx 10^(-11) "mol"/cancel"L" xx 1.222 cancel"L" = ???#
If this is regarding bromide anions, how many bromide atoms are in this? Highlight below to see the answer.
#color(white)(3.862 xx 10^(-11) cancel("mols Br"^(-)) xx (6.022 xx 10^23 "atoms")/cancel("1 mol anything ever"))#
#color(white)bb(= 2.326 xx 10^13 "atoms Br"^(-))#
