Answer:

2 moles of C-12 have 24g mass

Explanation:

Given data:

Number of moles of C-12= 2 mol

Mass of C-12 = ?

Solution:

Formula:

Number of moles = mass / molar mass

Molar mass of C-12 = 12 g/mol

Now we will put the values in formula.

2 mol  = mass / 12 g/mol

Mass = 2 mol ×  12 g/mol

Mass = 24 g

Thus 2 moles of C-12 have 24 g mass.
