The  volume  of the  gas  when  the  pressure  of  the  gas  increases  to  755mm  hg  is   calculated  as  follows

  by  use  of  boyles  law  formula  that  P1v1=P2V2
V2=  P1V1/P2
V1=5.58  L
P1=  715  mm  hg
P2=755  mm  hg
V2  is  therefore=   ( 715  mm  hg  x  5.58  L) /755  mm hg=  5.28 L

How many liters of 1.5 M potassium permanganate could be made if 152 g of the solute are available?
Misha Larkins [42]

Answer:

0.64 L

Explanation:

Recall that

n= CV where n=m/M

Hence:

m/M= CV

m= given mass of solute =152g

M= molar mass of solute

C= concentration of solute in molL-1 = 1.5M

V= volume of solute =????

Molar mass of potassium permanganate= 158.034 g/mol

Thus;

152 g/158.034 gmol-1= 1.5M × V

V= 0.96/1.5

V= 0.64 L
