Ca(OH)2
Molecular mass of calcium + 2 × Molar mass of oxygen + 2×molar mass of hydrogen
⇒ 40 + 2 × 16 + 2 × 1
⇒ 40 + 32 + 2
⇒ 74g/mol
Na2CO3:
2 × Molar mass of Na + Molar mass of carbon + 3×molar mass of oxygen
⇒ 2 × 23 + 12 + 3 × 16
⇒ 46 + 12 + 48
⇒ 106g/mol
Mm=22.9g/mol+35.4g/mol
=58.44277

send molicular mass of Nacl
plz
but as you know NaCl doesn't exist in the form of molecule
ok
so you have to find formula unit mass
