The dlope-intercept form:
m - slope
b - y-intercept (0, b)
The formula of a slope:
We have two points from the graph
x-intercept: (-1, 0)
y-intercept: (0, - 1) → b = -1
Substitute to the formula of a slope:
<h3>Answer: y = -1x - 1 = -x - 1</h3>
Answer:
0.013 M NaOH
Step-by-step explanation:
HCL + NaOH = NaCL + water
The mole ratio of acid and base is 1:1
Molarity is equal to the moles of solute divided by the liters of solution
Solute mole = 12.5 × 10^-3 × 0.3
= 0.003075
To neutralize 0.00375mol of HCl, 0.00375 mol of NaOH will be required. Since molarity is moles per liter, divide this amount of moles by the volume in liters:
Molarity = 0.00375/285 × 10^-3
Molarity = 0.0131 M
