B. The amounts of water and alcohol are not the same
Explanation:
Answer:
Sc(OH)₃ = 96 g/mol
Explanation:
Gram formula mass:
Gram formula mass is the atomic mass of one mole of any substance.
It can be calculated by adding the mass of each atoms present in substance.
Sc(OH)₃:
Atomic mass of Sc = 45 amu
Atomic mas of O = 16 amu
There are three atoms of O = 16 ×3
Atomic mas of H = 1 amu
There are three atoms of H = 1 ×3
Gram formula mass of Sc(OH)₃:
Sc(OH)₃ = 45 ×1 + 16 ×3 + 1 ×3
Sc(OH)₃ = 96 g/mol
Yes
