Answer:

Momentum = (mass) x (speed)

Mass is constant, so the rate of change of momentum is

(mass) x (rate of change of speed) .

But (rate of change of speed ) is just acceleration.

So the rate of change of momentum is (mass) x (acceleration).

But (mass) x (acceleration) is Force.

So Force is the rate of change of momentum. Verrrrrrrry interesting !

In this problem, Force = (40 kg) x (9 m/s²) = 360 newtons.

One 'Newton' is one kilogram-meter per second² .

Unit of momentum is (kilogram)-(meter per second), so 'newton'

is also a unit of time rate of change of momentum.

Rate of change of momentum is 360 momentum units per second.

If 6.35 g of cu(no3)2 is dissolved in water to make a 0.750 m solution, what is the volume of the solution (in ml)?

miv72 [106K]

First, we need to find out how many moles we have of $Cu ( NO_{3} )_{2}$ if we are given 6.35g.

We need to calculate the molar mass of the molecule:

Cu: 63.546g
N: 14.01g * 2 = 28.02g
O: 15.999g * 6 = 95.994

Add them together to get: 187.56g

So now we need to find the number of moles we are given. This can be done by setting up a multiplication equation and cancelling the units:

$\frac{1mole}{187.56g}* \frac{6.35g}{1}=0.034 mol _{Cu( NO_{3} )_{2} }$

So now that we know the number of moles that we have, we can use the molarity equation to find the volume of the solution. The molarity equation is:

$Molarity= \frac{moles}{Liters}$

So since we are given the molarity in the equation (0.750 M), we can plug in the molarity and moles to find the volume of the solution:

$0.750= \frac{0.034mol}{volume(L)}$

$volume(L)=0.04533L$

So now we know that the volume is 0.04533 Liters; however the question asks for the answer in milliliters. To do this, we must multiply by 1000:

$\frac{0.045L}{1} * \frac{1000mL}{1L}=45.33mL$

So the volume of the solution (<em>in mL</em>) is 45.33 mL.

The acceleration of gravity on the moon is 1.6 m/s2 and on earth it is 9.80 m/s2 if the weight of a moon rock is 125n what is it

ladessa [460]

At 6400 km above the earth’s surface, an object weighing 71 N on the surface would weigh only 18 N. Acceleration due to gravity will be about ¼ that on the surface of the earth.

What is the highest occupied molecular orbital in the O2 molecule?

Aleonysh [2.5K]

H2 is known to exist. For dihydrogen, H2, we can identify the frontier molecular orbitals (FMOs). The highest occupied molecular orbital (or HOMO) is the σ (sigma) 1s MO. The lowest unoccupied MO (LUMO) is the σ* (sigma star) 1s MO which is antibonding.
