iren [92.7K]

---  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.

A compound's molecular formula must always be different than the compound's empirical formula. TRUE FALSE
Juli2301 [7.4K]

Answer: False

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

Example: CH_4 has similar molecular formula and empirical formula as the elements are already present in simplest of the ratios.

C_2H_2 has molecular formula of C_2H_2 but CH as the empirical formula.

Consider the following reaction:
Goshia [24]

Answer:

2.01

Explanation:

First, let's convert grams to moles

(Na) 22.99 + (F) 18.998 = 41.988

Every mole of NaF is  41.988 grams

21/41.988 = 0.500143 moles of NaF

For every Cr+3, we will need 2 NaF, so Cr+3 will be half of NaF

0.500143/2 = 0.250071

molarity = moles/liters

0.250071/0.125 = 2.0057 M
