Answer:

9.804361662mols

n=m/M;

Where n=moles.

m=mass of the substance.

M=molar mass of the substance.

The mass, m was stated in the question which is 225.4grams.

The molar mass, M of sodium should have been given in the question which is 22.989768g/mol, this value can be obtained from the periodic table.

With these values given, you'll have to substitute the values into the formula then use arithmetic to arrive at the answer.

Echo Sound Company just began business and made the following four inventory purchases in June: June 1 150 units $ 1,040 June 10
postnew [5]

Answer:

FiFo method as prices are continuously increasing

Explanation:

Date                Units               Cost                    Per Unit Cost

June 1             150 units            $ 1,040               6.93

June 10           200 units              1,560               7.8

June 15          200 units               1,680               8.4

June 28          150 units               1,320               8.8

                                                  $5,600

As the unit price is increasing the method which yields the highest gross profit would be FIFO.But in some cases the income is overstated as the beginning inventory is too old to account for . Similarly Lifo gives lower net income but that too is not very beneficial when the inventory is almost obsolete.

The average method gives a measure in between FIFO and LIFO.

Juanita makes $42 an hour at work. She has to take time off work to purchase her skirt, so each hour away from work costs her $4
Kisachek [45]

Answer:

It will purchase at the local store at an economic cost of $123

Explanation:

Answer:

It will puchase the skirt across town as it has the less economic cost.

Explanation:

We are going to add up the opportunity cost (lost wages) to the cost of the skirt:

place          travel-time Price Cost to travel Economic Cost

local store       30  $ 102.00   $ 21.00   <u> $ 123.00 </u>

across town       60  $ 85.00   $ 42.00   $  127.00

neighboring city 120  $ 76.00   $ 84.00   $ 160.00

*travel-time we multiple the time it took each eway by 2

**The  cost to travle will be Juanitas wages per hour ($42) times the travel-time/ 60

That's because the wages are express in hours and the travel time in minutes so we convert into hours

Then, the economic cost is the sum of the value of the skirt and the lost wages.

<em>Juanita, as a rational consumer will chose to purchase at the lower cost.</em>
