<h2> The amount of Hcn formed in grams is = 0.06223 grams</h2><h3> calculation</h3>
write the equation for reaction
that is; KCn + HCl → KCl + HCn
step 1:find the moles of KCn reacted
moles of KCn = mass of KCn/molar mass of KCn( 65.12 g/mol)
= 0.150 g/ 65.12 g/mol =2.303 x10^-3 moles
step 2: use the mole ratio between KCn :HCn which is 1:1 to determine the moles of HCn which is also 2.303 x 10^-3 moles
step 3: find the mass of HCn =moles of HCn x molar mass of HCn
= 2.303 x10^-3 x 27. 02 =0.06223 grams

Hope this helped!
One kilogram is equal to one thousand grams. Further, one gram is equal to 1000 mg. The conversion is as shown below,
(6.285 x 10³ mg) x (1 g / 1000 mg) x (1 kg / 1000 g)
The numerical value of the operation above is 0.006285 kg.
