Answer:
600.7 moles
Explanation:
Applying,
PV = nRT................... Equation 1
Where P = Pressure of oxygen, V = Volume of oxygen, n = number of moles, R = molar gas constant, T = Temperature.
make n the subject of the equation
n = PV/RT............... Equation 2
From the question,
Given: P = 190 atm, V = 35 L, T = 135 K
Constant: R = 0.082 atm.dm³/K.mol
Substitute these values into equation 2
n = (190×35)/(135×0.082)
n = 600.7 moles of xygen

Answer:
Objects with the same charge repel each other, and objects with opposite charges attract each other.
Explanation:
The Coulomb law states that opposite charges attract each other and like charges repel each other. That means two positive charges repel each other but a positive and a negative charge attract.
Gravity is the force that draws water back to the earth in the forms of rain, sleet and, snow.
