Hope I helped!
Answer:
110k because 2 x 110 =220
Answer:
178.1g
Explanation:
m= n × MM
where
m is mass
n is moles &
MM is molecular mass
The molecular mass of cobalt is 58.933195. With this information and the number of moles given in the question, we can perform the calculation
m= 3.022 × 58.933195
m=178.09611529
m= 178.1g
The relative abundance and the mass number usually they give these to you. They give me both these values in my chemistry class so i just multiply add the products and get my answer
