Answer:
4.79 g
Step-by-step explanation:
mass of salicylic acid = ??
Mass of polyethylene = 75 g
% w/w concentration = 6% w/w
Let the mass of salicylic acid be x
Let the mass of solution = 75 + x
from
% w/w = mass of solute/ mass of solution * 100
Hence concentration of salicylic is;
6 = (x/75 + x) * 100
6/100 = x/75 + x
0.06 (75 + x) = x
4.5 + 0.06x =x
4.5 = x-0.06x
x = 4.5/0.94
x= 4.79 g
5 (5/8) * 1 (5/9) = 45/8 * 14/9 = 630/72 = 8 (54/72) = 8 (3/4) miles
Answer: P = 19,571.42857142857
Step-by-step explanation:
Plug in the variables.
5480 = x(.04)(7)
.04*7=.28
5480=.28x
.28x/.28=x
5480/.28=19,571.42857142857
19,571.42857142857(.04)(7)=5480
P = 19,571.42857142857
