First let us calculate the initial molarity of the 2.45 L
of solution. Molar mass = 171.34 g/mol
<span>moles Ba(OH)2 = 74.28 g * (1 mole / 171.34 g) = 0.4335 moles</span>
Molarity (M1) = 0.4335 moles / 2.45 L = 0.177 M
Now using the formula M1V1 = M2V2, we can calculate how
much to dilute (V1):
0.177 * V1 = 0.1 * 1
V1 = 0.56 L
<span>Therefore 0.56 L of the initial solution must be diluted
to 1 L to make 0.1 M</span>
Answer:
Gneiss forms by regional metamorphism from both high temperature and pressure. Quartzite and marble are the most commonly used metamorphic rocks.
Answer: 101 moles of oxygen are contained in the tank
Explanation:
According to ideal gas equation:
P = pressure of gas = 204.047 atm
V = Volume of gas = 12.0 L
n = number of moles = ?
R = gas constant =
T =temperature =
Thus 101 moles of oxygen are contained in the tank
