$0.538$ $"g"$ $""^13"C"$

Explanation:

We're asked to find the number of moles of $""^13"C"$ that has a mass of $7.00$ $"g"$ .

Carbon-13 is merely an isotope of carbon, and its isotopic mass is $13.003$ $"amu"$ (from a source), which means its molar mass is $13.003$ $"g/mol"$ .

Thus, we use this molar mass when performing our conversion from mass to moles:

$7.00cancel("g"color(white)(l)""^13"C")((1color(white)(l)"mol"color(white)(l)""^13"C")/(13.003cancel("g"color(white)(l)""^13"C"))) = color(red)(ul(0.538color(white)(l)"mol"color(white)(l)""^13"C"$
