Answer:
The new molarity is 0,1359M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We use the formula for dilutions:
C1 x V1 = C2 x V2
0,60 M x 0,639 L= C2 x 2,822 L
C2=(0,60 M x 0,639 L)/ 2, 822 L
<em>C2=0,1359 M</em>
Answer: sulfer
d = 0.93 g/cm³
Given data:
Mass of object = 28 g
Volume of object = 3cm×2cm×5cm
density of object = ?
Solution:
Volume of object = 3cm × 2cm ×5cm
Volume of object = 30 cm³
Density of object:
d = m/v
by putting values,
d = 28 g/ 30 cm³
c
the rate of a forward process must be exactly balanced by the rate of the reverse process.
