What mass of sodium chloride contains 4.59 exp24 formula units?
The gram formula unit mass of sodium chloride is 58.443, and every gram formula unit mass contains Avogadro's Number, 6.022 X 1023 formula units. Therefore, the mass sought is 58.443 X (4.59 X 1024)/(6.022 X 1023) or 445 grams, to the justified number of significant digits.
What must you know to determine which of two vehicles traveling at the same velocity has the greater momentum?
To determine which vehicle has the greater momentum, you need to know the mass of each vehicle. Momentum is defined as momentum = mass x velocity, so the vehicle with the greater mass will have the greater momentum. If the vehicles have the same mass, then they will have the same momentum.
If crystal salt has a mass of 0.12 g how many NaCl formula units does it have?
1.24 x 10 (18th) molecules .12mg x 1g/1000mg x 1mol/58.443g (molar mass of NaCl) x 6.022 x 10(23rd) molecules/1mol =1.236 x 10 918) molecules :) hope this helps! -forensics major currenly!!
How many formula units are there in 2.45 moles potassium chloride?
To determine the number of formula units in 2.45 moles of potassium chloride, you first need to find the molar mass of KCl, which is approximately 74.55 g/mol. Then, divide the number of moles by the molar mass to get the number of formula units. Therefore, 2.45 moles of KCl is equivalent to about 163 formula units.
How much is mass?
This is determined by Einstein's equation E = mc2, where c = velocity of light = 3 x 108 meters/sec. So c2 = 9 x 1016. For 1 kg of mass therefore the equivalent energy is 9 x 1016 Joules, for 1 gram it is 9 x 1013 Joules.Note units, in the SI system energy is in Joules, mass in kg, distances in meters. If you keep to these units you will get consistent results.The above of course only holds for the complete annihilation of 1 gram or 1 kilogram of mass, which does not happen in chemical reactions, so don't try to apply it in such cases!
What are the units you use for measuring a moment?
If you mean a brief moment of time: seconds.If you mean momentum: this is mass x velocity, so the units are kg x meters / secondsIf you mean a brief moment of time: seconds.If you mean momentum: this is mass x velocity, so the units are kg x meters / secondsIf you mean a brief moment of time: seconds.If you mean momentum: this is mass x velocity, so the units are kg x meters / secondsIf you mean a brief moment of time: seconds.If you mean momentum: this is mass x velocity, so the units are kg x meters / seconds
Is momentum the same as force yes or no?
It is not, and it doesn't even have the same units. Momentum has the units of force x time (or equivalently, mass x velocity).
M omentum is expressed in units of?
Momentum is defined as mass times velocity, and it requires units of mass times units of velocity. The SI unit is kilograms x meters / second. There is no special name for this combination of units.
What is the units for moments?
Since moment is mass x velocity, you need corresponding units. For example, in the SI, kg x meters / second.
What is formula of momentum?
The units are KgMs- why? Velocity is a vector Quantity and mass is a scalar quantity.
How many Kilogram are in 1.27 x the exponent of 4?
None. A kilogram is a measure of mass. The 1.27 x etc is a pure number and has no units of mass associated with it.
How do you calculate the momentum of a truck rolling down a hill?
You can calculate the momentum of a truck rolling down a hill by multiplying its mass by its velocity. Momentum = mass x velocity. Make sure to use consistent units for mass (kg) and velocity (m/s) in your calculation.
What are Units of particle motions?
"Motion" can be expressed in units of speed. Or it might refer to momentum - in which case you would use any unit of mass x velocity.
How do you find momentum with mass and speed?
Momentum is calculated by multiplying an object's mass by its velocity. The formula for momentum (p) is: p = mass (m) x velocity (v). Make sure to ensure that mass is in kilograms and velocity is in meters per second to keep consistent units.
What does momentum of an object mean?
Momentum is the product of mass x velocity.
How are mass and velocity related to momentum?
Momentum is directly proportional to both mass and velocity. This means that an object with a larger mass or a higher velocity will have a greater momentum. The formula for momentum is momentum = mass x velocity.
What is momentum divided by velocity?
Momentum = mass x velocity. If you divide out the velocity you get mass.
