Answer:
The question asks for moles, which can be obtained from P-V-T data using the ideal gas
equation: n =
RT
PV .
Now use the rearranged gas law to determine the number of moles in the sample:
!
n = PV
RT = (6.47 x 105 Pa)(5.65 x 10-4m3
)
(8.314 J
mol K )(21.7 + 273.15 K) = 0.149 mol.
All conditions except the pressure and volume are fixed, so P1V1 = P2V2 can be used: 3.62 L
101kPa
(647 kPa)(0.565 L)
2
1 1
2 = =
P
PV V

Answer:
The pricing strategy is an important element in setting up the selling price of a product.
Explanation:
The pricing strategy is an important consideration while fixing up the selling price of product manufactured. When setting up a selling price of a product, the companies set up product calculation. Businesses should decide the pricing strategy before they advertise the products to the customers.
There are mainly 5 benefits to the businesses while doing a product calculation. They are:
--- Doing competition based pricing enables the company to compete with the rival companies product and is based on the market based study. Competition pricing is a useful tool for the retailers as well as the small businesses.
--- Doing a cost plus pricing helps the total cost of making the product and also an add up in the market in order to determine the pricing of the product.
--- Dynamic pricing :
Dynamic pricing is a non static pricing. Dynamic pricing is an efficient method for the market based on the supply and demand.
--- Penetration pricing :
Penetration pricing is used by the large companies which is used to capture the market share by the setting product prices at the below market level so as to gain customers.
--- Doing a research for the price skimming helps the company to set up the accurate price for the product rather than readjusting the prices of the product later on based on the demand and the supply.
<u>Charge:</u>
An electron has a negative charge and a <em>n</em>eutron has a <em>n</em>eutral charge.
<u>Size:</u>
Electrons have a really small mass whereas the neutron has a mass of about 1 amu.
<u>Location:</u>
Neutrons are found in center of an atom, but electrons are around it.
<u>Number:</u>
The number of electrons and neutrons in atom varies.
The element can also be called gold-197. It has Mass number
is 197, atomic number is 79 and electrons 79, Atoms that have the same number
of protons but different number of neutrons. Isotopes have identical numbers of
protons and electrons.
Answer:
f = V / λ
Explanation:
In this formula, f represents frequency, V represents the velocity of the wave, and λ represents the wavelength of the wave
