A chemist wishes to mix a solution that is 12​% acid. She has on hand 14 liters of a 6​% acid solution and wishes to add some 16
Maslowich

Answer:

25 liters of the 16% solution should be added.

Step by Step Explanation:

pure acid amount + pure acid amount = total pure acid amount

So,

0.02*10 + 0.16*x = 0.12*(10+x)    

0.02*10 + 0.16x = 0.12*10 + 0.12*x

0.16*x - 0.12*x = 0.12*10 - 0.02*10

(0.16 - 0.12)*x = 0.12*10 - 0.02*10

x = (0.12*10-0.02*10)/(0.16-0.12)=25

Check:   (0.2*10+0.16*25)/(10+25) = 0.12 = 12% of concentration of the final mixture.   ! Correct !

If you use 1 mole of NaOH, how much NaAl(OH)4 is produced
abruzzese [7]
Answer:
             81.97 g of NaAl(OH)₄

Solution:
              The reaction for the preparation of Sodium Aluminate from Aluminium Metal and NaOH is as follow,

                 2 NaOH  +  2 Al  +  6 H₂O    →    2 NaAl(OH)₄  +  3 H₂

According to this equation,

          2 Moles of NaOH produces  =  163.94 g (2 mole) of NaAl(OH)₄
So,
       1 Mole of NaOH will produce  =  X g of NaAl(OH)₄

Solving for X,
                     X  =  (1 mol × 163.94 g) ÷ 2 mol

                     X  =  81.97 g of NaAl(OH)₄
