Calculate the molarity and the pH.
1.11g of KOH in 908 mL H2O
1.2g of HNO3 in 2111 mL H2O
Molarity is defined as moles per litre
So convert g of KOH to moles of KOH
Moles of KOH = mass of KOH /Molar mass of KOH
Convert volume in Litres
1000mL =1L
Now plug it in molarity formula
M=Moles/Volume in Litres
1.2g of HNO3 in 2111 mL H2O
Convert g of HNO3 to moles of HNO3 (molar mass of HNO3 is 63 g )
and mL of water to litres of water
Divide moles of HNO3 with litres of water
