Answer:

A. Second

Explanation:

The S.I unit of time is in Seconds.

The S. I unit is known as the metric system is the most commonly used system of reporting scientific measurements in the world today. Other units are the imperial units.

It is the international system of unit used in almost all countries. The seven basic SI units are:

        Quantities                                    Units

  • Length                                         meters(m)    
  • Time                                            seconds(s)
  • Amount of substance                 moles(mol)
  • Mass                                            kilograms(kg)
  • Luminous intensity                     candela(cd)
  • Temperature                               kelvin(K)
  • Electric current                            ampere(A)

The SI unit of time which measures the duration of an activity or event is therefore given as seconds(s)

Given the NaOH density =1.0698g mL^-1, How many mL of .71M HCl would be required to neutralize 11.33g of 2.03 M NaOH?
SSSSS [86.1K]

 The volume in ml of 0.71 M HCl  that would  be  required to neutralize  11.33 g   of 2.03 M NaOH  is 30.3 ml

<u><em>calculation</em></u>

Step 1 : write equation  for reaction

NaOH + HCl →NaCl +H₂O

Step 2:find the volume of NaOH

volume=mass/ density

= 11.33 g/ 1.0698 g/ml  =10.59 ml

Step 3: find the  moles of NaOH

moles  = molarity  x volume  in liters

molarity= 2.03 M=2.03 mol/l

volume  in liters =10.59/1000 =0.0106 L

moles  = 2.03 M  x 0.0106 L =0.0215  moles

step 4:  use the mole ratio to determine the moles of HCl

from  equation in step 1 , NaOH:HCl  is 1:1 therefore the moles of HCl is also 0.0215  moles

Step 5: find volume of  HCl

volume= moles/ molarity

molarity  =0.71 M =0.71 mol/l

=0.0215 moles /0.71  mol/l=0.0303 L

into ml =0.0303 x 1000=30.3 ml
