Answer : The correct option is, (D) Velocity
Explanation :
Velocity : It measures the speed of an object in a particular direction. It is a vector quantity. It depends on the magnitude and the direction. The S.I unit of velocity is, 
Distance : It measures the length between the two objects. The S.I unit of distance is, meter.
Speed : It is defined as the distance traveled per unit of time. It does not have a direction. The S.I unit of speed is,
Acceleration : It is defined as the rate of change of velocity of an object with respect to time. The S.I unit of acceleration is, 
Hence, the motion we can determine from the given data is, velocity.
Hey there!
The sample of NF₃ contains 8.02 moles fluorine atoms.
There are 3 fluorine atoms in each molecule, so there will be 1/3 of the moles of fluorine.
8.02 / 3 = 2.67
There are 2.67 moles of NF₃ in a sample that contains 8.02 moles fluorine atoms.
Hope this helps!
Using the given formula, the density of the material is 2.015 g/mL
<h3>Calculating Density </h3>
From the question, we are to determine the density of the material
From the given formula
Density = Mass / Volume
And from the given information,
Mass = 65.5 g
and volume = 32.5 mL
Putting the parameters into the equation,
Density = 65.5/32.5
Density = 2.015 g/mL
Hence, the density of the material is 2.015 g/mL.
