You have 1169.6 g of a bleach solution. The percent by mass of the solute sodium hypochlorite, NaOCl, is 3.62%. How many grams o
Aneli [31]

Answer:

Mass of solvent is 1127.3 g

Explanation:

NaOCl → 3.62%

This percent means, that in 100 g of bleach solution, there are 3.62 g of NaOCl. So let's make a rule of three:

100 g of bleach solution have 3.62 g

1169.6 g of bleach solution may have (1169.6  . 3.62) /100 = 42.3 g

42.3 g is the mass of NaOCl in the solution

Mass of solution = Mass of solvent + Mass of solute

1169.6 g = Mass of solvent + 42.3 g

1169.6 g - 42.3 g = Mass of solvent → 1127.3 g

What is the rate constant of a reaction if rate = 0.2 (mol/L)/s, [A] and [B] are each 3 M, m = 1, and n = 2?
tino4ka555 [31]
M= 1 and n = 2
( m+ n =  1 +2  = 3)

rate = K [A] [B]^2

0.2  = K *  3  * 3 ^2
0.2 =  K  *  3 * 9 
 K =    0.2   / 27 
K =   7.408 *  10 ^ -3  m^-2  s^-1
