Answer:
<h3>The answer is 6 moles</h3>Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>6 moles</h3>Hope this helps you
Answer:
Explanation:
The density formula is
Rearrange the formula for mass, m, by multiplying both sides of the equation by v.
The mass can be found by multiplying density and volume.
The density of the sugar is 1.59 grams per milliliter. The volume is 237 milliliters.
Substitute the values into the formula.
Multiply. Note that the milliliters, or mL will cancel each other out.
The mass is 376.83 grams.
The ball's potential energy will decrease, and its kinetic energy will increase.
Explanation:
The ball's potential energy will decrease down the slope and its kinetic energy will increase.
Kinetic energy is the energy due to the motion of a body.
K. E = m v²
m is the mass of the ball
v is the velocity of the ball.
Potential energy is the energy due to the motion of a body down slope.
It is expressed as:
P.E = mgh
m is the mass of ball
g is the acceleration due to gravity of the body
h is the height.
We can see as the body drops down the slope, the height diminishes and the velocity increases.
