Question

Calculate mass of 0.5 moles of HCL​

Answer 1

Moles=0.5

Hcl molecular mass=17+1=18


No of mole=mass/mol. mass


0.5=mass/18
mass=0.5×18
9gm


9grams is mass of HCL

Answer 2

Answer: 18.25 g :)

Explanation:

By formula,

No. of moles = Given mass/ molecular mass

Molecular mass of HCl = 1+ 35.5

= 36.5

Given Moles = 0.5

Therefore, given mass = moles × mol. mass

= 0.5 × 36.5

= 18.25 g
