Question

‼️I WILL MARK BRAINLIEST

Answer 1

Ba(OH)2 + 2 HNO3 -----> Ba(NO3)2 + 2 H2O

1) Calculate moles of Ba(OH)2 used.

0.65 mol / L x 0.0234 L = 0.01521 mol Ba(OH)2

2) Calculate moles of HNO3 used.

0.01521 mol Ba(OH)2 x 2 HNO3 / 1 Ba(OH)2 = 0.03042 mol HNO3

3) Calculate molarity of HNO3.

0.03042 mol / 0.0425 L =

so the answer is 0.716 M !
