Answer:
1.48381734165x 10²⁵ molecules
Explanation:
1 grams CuNo3 is equal to 0.0011897028836018 mole.
x = 5.5 moles
x = 5.5 x 1/0.0011897028836018 = 5.5/0.0011897028836018
4623.003grams
the molar mass of cuno3 =187.56 = 6.02 x10²³
4623.003g = x
187.56x = 4623.003 x 6.02 x10²³ = 27830.47806 x10²³ = 1.48381734165x 10²⁵
