Mol Ca(OH)2 = V × M = 75 × 1,3 = 97,5 mmol
Ca(OH)2 +HNO3 --> Ca(NO3)2 +H20
Setarakan
Ca(OH)2+2HNO3-->Ca(NO3)2+2H20
Perbadingan koefisien sebanding dengan mol, maka
Koef Ca(OH)2 = mol Ca(OH)2
__________ ___________
Koef HNO3 mol HNO3
1/2 = 97,5 / mol HNO3
1× mol HNO3 = 97,5 × 2
Mol HNO3 = 97,5 × 2 = 195 mmol
M = n ÷ V = 195 ÷ 25 = 7,8 M
