Show full solutionCorrect answer: 1.1
Correct answer
1.1
Step-by-step explanation
Mass of NaOH = x
Moles of NaOH =
Mass of Na2CO3 = y
Moles of Na2CO3 =
x + y = 4
x = 1.1, y = 2.9
x = 1.1 1 (nearest integer)
Moles of NaOH =
Mass of Na2CO3 = y
Moles of Na2CO3 =
x + y = 4
x = 1.1, y = 2.9
x = 1.1 1 (nearest integer)
