Answer:
4.332 millimoles of NaOH
Explanation:
Molarity (M) = moles per liter (mole/L); liters x moles/liter = moles
0.04332 L x 0.1 mole/liter = 0.004332 moles of NaOH (4.332 millimoles)
millimoles / milliliters = moles/liter = molarity (M).
4.332 millimoles / 50 milliliters = 0.08664 M HCl
In the Volumetric titration at the end point, moles of NaOH = moles of HCl
NaOH + HCl --> H2O + NaCl
Answer:
0.35 M
Explanation:
Molar mass of calcium chloride= 40+2(35.5)= 111gmol-1
Mass calcium chloride= 21.84g
Volume of solution= 562.43ml
From
n= CV
But n=m/M
n= number of moles
C=concentration
V= volume of solution in litres
m=mass of substance
M= molar mass of substance
n=21.84/111= 0.197moles
C= 0.197 ×1000/562.43
C= 0.35 M
Answer: The correct answer is
Earthquakes occur along fault lines, cracks in Earth's crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose.
