Answer:
151.5g
Step-by-step explanation:
This is because the grams in one mole of a substance simply equate to its molecular mass. The molecular mass of Scandium (Sc) is 45. The molecular mass of Chlorine (Cl) is 35.5. And because there are 3 atoms of Cl we multiply 35.5 times three.
simply put:
45+3(35.5)=151.5g
