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.
