Q31 of 75 Page 81

Calculate the mass of each of the following:

10 moles of hydrogen cyanide

Given: Number of moles = 10


Atomic mass of HCN = 1+ 12 + 14 = 27g/mol


To find out the mass of hydrogen cyanide, apply the formula given:



⇒


⇒ Mass = 10 mol × 27g/mol


⇒ Mass = 270g


Thus, the mass of hydrogen cyanide is 270g.
