Answer:

There are #"1.16 mol Co"# in #6.97xx10^23# atoms of Co.

Explanation:

Identify the relationship between 1 mol Co and Avogadro's number of atoms.

#"1 mol Co"##=##6.022xx10^23"atoms Co"#

Divide the given atoms of cobalt by the number of atoms per mol.

#6.97xx10^23cancel"atoms Co"xx("1 mol Co")/(6.022xx10^23cancel"atoms Co")="1.16 mol Co"#
