Question

relative molecular mass of Na Cl

Answer 1

Answer:

hope it help you in some way

Answer 2

Answer:-

• Atomic mass of Sodium=Na=23u
• Atomic mass of Chlorine=Cl=35u

Molecular mass

$\\ \qquad\sf\longmapsto Molecular\:Mass=1(23u)+1(35u)$

$\\ \qquad\sf\longmapsto Molecular\:mass=23u+35u$

$\\ \qquad\sf\longmapsto Molecular\:Mass=58u$

$\\ \underline{\boxed{\bf{\therefore Molecular\:Mass\:of\:NaCl=58u.}}}$
