Question

Calculate the mole of 73 grams of HCL

Answer 1

Molecular Mass:-

$\\ \sf\longmapsto HCl$

$\\ \sf\longmapsto 1u+35u$

$\\ \sf\longmapsto 36u$

Now

No of moles in 73g of HCl:-

$\\ \sf\longmapsto No\:of\:moles=\dfrac{1}{73}\times 36$

$\\ \sf\longmapsto No\:of\:moles=\dfrac{73}{18}$

$\\ \sf\longmapsto No\:of\:moles=4.05moles$
