Answer:
M1 = 6.0M
V1 = 8.33mL
M2 = 1.0M
V2 = 50.0mL
Explanation:
It is possible to find the volume that we need to prepare a diluted solution from a stock using the equation:
M1V1 = M2V2
<em>Where M is molar concentration and V volume of 1, stock solution and 2, diluted solution.</em>
Replacing:
M1 = 6.0M
V1 = Our incognite
M2 = 1.0M
V2 = 50.0mL
6.0M*V1 = 1.0M*50.0mL
V1 = 1.0M * 50.0mL / 6.0M
V1 = 8.33mL of the stock solution are needed
Answer:
V=20.2m3
Explanation:
P= 225.4kPa V= ? n= 1.85, T= 22.5+273= 295.5K, R = 8.314
Applying the ideal gas equation
PV=nRT
225.4×V = n×8.314×295.5
V= 20.2m3
Answer:
Na2S
Explanation:Just took the test
The resulting pressure of the gas after decreasing the initial volume is 3 atm.
<h3>What is
Boyle's Law?</h3>
According to the Boyle's Law at constant temperature, pressure of the gas is inversely proportional to the volume of the gas:
P ∝ 1/V
For the given question required equation is:
P₁V₁ = P₂V₂, where
P₁ = initial pressure = 1.5 atm
V₁ = initial volume = 2 L
P₂ = final pressure = ?
V₂ = final volume = 1 L
On putting all these values on the above equation, we get
P₂ = (1.5)(2) / (1) = 3atm
Hence required pressure is 3 atm.
