Determine the mass of chloride (mw = 35.45 g/mol ) in grams present in 100 ml of a 0.325 m solution of aqueous ticl3 (titanium(iii) chloride).

 The  mass   chloride is  3.456 grams

 calculation

 Step:1 calculate the moles of TiCl3

moles = molarity  x  volume  in liters

volume in liters = 100 ml /1000 =  0.1 L

molarity = 0.325  M  =  0.325  mol / L

moles  is therefore  =  0.1 L x  0.325  mol /L = 0.0325   moles

step 2: find the moles of Cl

since there is  3  atoms of  cl in TiCl3  the moles of Cl

= 3 x 0.0325 =0.0975 moles

Step 3:  calculate  mass  of cl

 mass= moles  x molar mass

=0.0975 moles x 35.45 g/mol = 3.456 g

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
