La masa molar de 65 litros de SO2 es igual a 64,1 g/mol.
<h3>Masa molar</h3>
La masa molar de un compuesto depende de su masa presente en 1 mol, entonces:

Para calcular la masa molar de un compuesto, simplemente suma las masas de cada elemento en el compuesto, así:

Explanation:
Assuming the initial point P1 of this vector is at the origin:
P1=(X1,Y1)=(0,0)
And knowing the other point is P2=(X2,Y2)=(19.5,28.4)
We can find the magnitude and direction of this vector, taking into account a vector has a initial and a final point, with an x-component and a y-component.
For the magnitude we will use the formula to calculate the distance
between two points:
(1)
(2)
(3)
(4) This is the magnitude of the vector
For the direction, which is the measure of the angle the vector makes with a horizontal line, we will use the following formula:
(5)
(6)
(7)
Finding
:
(8)
(9) This is the direction of the vector
Answer:
The force exerted by the floor is 80 N.
Explanation:
Given that,
Mass of ball = 0.5 kg
Velocity= 4 m/s
Time t = 0.05 s
When the ball rebounds then the kinetic energy is

Where, m = mass of ball
v = velocity of ball
Put the value into the formula


The average force exerted by the floor on the ball = change in kinetic energy over collision time


Hence, The force exerted by the floor is 80 N.
