Known :
V1 = 300 mL
M1 = 0.75 M
M2 = 0.25 M
Solution :
M1 • V1 = M2 • V2
(0.75 M) • (300 mL) = (0.25 M) V2
V2 = 900 mL
Water add to this solution is :
∆V = V2 - V1
∆V = 900 - 300
∆V = 600 mL
The atoms on the outermost level are called electrons.
Answer:
ΔG = 18KJ/mol
Explanation:
Given data:
ΔS = 0.09 Kj/mol.K
ΔH = 27 KJ/mol
Temperature = 100 K
ΔG = ?
Solution:
Formula:
ΔG = ΔH - TΔS
ΔH = enthalpy
ΔS = entropy
by putting values,
ΔG = 27 KJ/mol - 100K(0.09 Kj/mol.K)
ΔG = 27 KJ/mol - 9 KJ/mol
ΔG = 18KJ/mol
Answer:
Most of these rocks are not made up of common geometric shapes
Explanation:
Because most rocks are not made up of common geometric shapes, it would be difficult or impossible to find the volume of a rock using a ruler; there would be no easy way to measure the rock's volume using a ruler
Hope this helped!
