Answer:
95.21
Explanation:
Magnesium has a molar mass of 24.31 and CHlorina has a molar mass of 35.45. Since there are 2 Cl you add 35.45 to 35.45= 70.9. Then add the 24.31 for Magnesium. 70.9 + 24.31= 95.21.
Answer: 94 g MgCl2
Explanation:
The atomic mass of Mg is 24g and Cl is 35. There are 2 atoms of Cl in the formula so multiply it by 2
24 + 35x2 = 94
