Answer:
Number of moles of CoCl3 = 0.09 moles
Explanation:
Given data:
Mass of CoCl₃ = 12.1 g
Number of moles = ?
Solution:
First of all we will calculate the molar mass.
Molar mass of CoCl3 = 28.01 + (35.5×3)
Molar mass of CoCl3 = 28.01 + 106.5
Molar mass of CoCl3 = 134.51 g/mol
Number of moles of CoCl3 = mass / molar mass
Number of moles of CoCl3 = 12.1 g/134.51 g/mol
Number of moles of CoCl3 = 0.09 moles
Answer:
Mass= volume x density
Explanation:
Multiply the density by the volume.
The answer is c.......................................
9,353 - 1,095 - 5,217 = mN
3,041 = mN
H:C:N= 1,095/1 : 5,217/12 : 3,041/14
H:C:N = 1,095 : 0,43475 : 0,2172
H:C:N = 5,037 : 1,99985 : 0,99912 ≈ 5 : 2 : 1
H₅C₂N (C₂H₅N)
I don’t even know that’s just weird
