Question

question 8 of 10
4 cacl₂
calcium chloride
how many total atoms are in 4 cacl₂?
12 atoms
3 atoms
2 atoms
4 atoms

Explanation:

Step1: Analyze atoms in one $CaCl_2$

One $CaCl_2$ has 1 calcium (Ca) atom and 2 chlorine (Cl) atoms, so 1 + 2=3 atoms in one $CaCl_2$.

Step2: Calculate atoms in 4 $CaCl_2$

Since there are 3 atoms in one $CaCl_2$, for 4 $CaCl_2$, we multiply the number of atoms in one by 4, so 3×4 = 12 atoms.

Answer:

12 Atoms
