582 ml is the volume of gas.
Answer:
Explanation:
Using the ideal law of gases, the kinetic theory of gas can be stated as
PV = nRT
Here P is the pressure and it is given as 1.2 atm, V is the volume, which we need to find. Then R is the gas constant and T is the temperature while n is the concentration present.
As per the give question, P = 1.2 atm, T = 140 K and n = 0.5 moles, R = 8.314
V = 
V = 
So 582 ml is the volume of gas.
First factor: Density of water
This density of water is affected by the level of salt present in it. They are inversely proportional. This means that as the amount of salt in water increases (water becomes more salty), the density of water would decrease
Second factor: Temperature
Temperature affects the composition of water because as temperature increases, the ocean water evaporates and the salt precipitates. Therefore, this factor is essential in determining the rate by which the ocean water evaporates
Third factor: Salinity
This factor helps in determining the amount of salt present in the ocean, i.e, concentration of salt in the water.
Hope this helps :)
Answer:
1.301 × 10⁻¹² m
Explanation:
Step 1: Given and required data
- Energy of the electromagnetic wave (E): 1.528 × 10⁻¹³ J
- Planck's constant (h): 6.626 × 10⁻³⁴ J . s
- Speed of light (c): 3.00 × 10⁸ m/s
Step 2: Calculate the wavelength (λ) of the electromagnetic wave
We can calculate the wavelength of the electromagnetic wave using the Planck-Einstein's relation.
E = h × c / λ
λ = h × c / E
λ = (6.626 × 10⁻³⁴ J . s) × (3.00 × 10⁸ m/s) / 1.528 × 10⁻¹³ J
λ = 1.301 × 10⁻¹² m
Answer:-
190.23 gram mol-1
Explanation:-
Molar mass is the mass of 1 mole of that substance. It's unit is gram / mol or gram mol-1.
For an element it is equal to it's atomic weight.
The atomic weight of Osmium is 190.23
Hence the molar mass of Osmium is 190.23 gram / mol
