Explanation:

if helps mark as brainliest

Answer 2

Answer:

Molecular mass of Ca(OH)

Molecular mass of Ca(OH) 2

Molecular mass of Ca(OH) 2

Molecular mass of Ca(OH) 2 =1(Atomic mass of Ca)+2(Atomic mass of O) +2(Atomic mass of H)

Molecular mass of Ca(OH) 2 =1(Atomic mass of Ca)+2(Atomic mass of O) +2(Atomic mass of H) =40+2(16)+2(1)

Molecular mass of Ca(OH) 2 =1(Atomic mass of Ca)+2(Atomic mass of O) +2(Atomic mass of H) =40+2(16)+2(1) =40+32+2

Molecular mass of Ca(OH) 2 =1(Atomic mass of Ca)+2(Atomic mass of O) +2(Atomic mass of H) =40+2(16)+2(1) =40+32+2 =74
