Answer:
178 torr
Explanation:
Using Ideal gas equation for same mole of gas as
Given ,
V₁ = 5 mL
V₂ = 5 mL (Closed container)
P₁ = 95.0 torr
P₂ = ?
T₁ = 28.0 ºC
T₂ = 290 ºC
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (28 + 273.15) K = 301.15 K
T₂ = (290 + 273.15) K = 563.15 K
Using above equation as:
Solving for V₂ , we get:
P₂ = 178 torr
Answer:
The molecular weight (molar mass) of any gas is the mass of one particle of that gas multiplied by Avogadro's number (6.02 x 1023).
Explanation:
How do you find the molar mass of a gas?
First the ideal gas law will be used to solve for the moles of unknown gas (n). Then the mass of the gas divided by the moles will give the molar mass.
Answer:
The law of conservation of matter says that matter cannot be created or destroyed. In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products
Explanation:
Answer:
cutting, bending, dissolving, freezing, and boiling
Explanation:
A physical change is a change in one or more physical properties of matter without any change in chemical properties. In other words, matter doesn't change into a different substance in a physical change. Examples of physical change include but are not limited to, from solid to liquid or from liquid to gas are also physical changes.
