Strategy:
 stoichiometry relates the moles of  needed to the moles of  produced ( ratio). Convert the target mass to moles, apply the ratio, and convert back to mass.

Step 1: Calculate moles of } \ce{KNO3}
Molar mass .

Step 2: Calculate required moles of } \ce{HNO3}
From the equation: 4 moles  moles .

Step 3: Calculate mass
Molar mass .
