To calculate for mass, simply multiply molar weight (MW) and number of mols. The molar weight (MW) is in units of mg / mmol. Therefore the mass is:

mass = (158 mg / mmol) (0.25 mmol)

mass = 39.5 mg

 

Answer:

39.5

Ashley should get her seeds at garden place as she gets the exact amount of seeds and spends the least amount of money.
first of all I divided 75 by the amount of seeds you get it a packet. then if that was a decimal I rounded it to the larger number (eg. 7.15 rounded to 8)
then I multiplied the cost by that number to get the amount of money itd cost.
so I got in order of the boxes(s=seeds)
75s=$18
80s=$18.4
84s=$21.84
80s=$20
so the best deal is Garden place

Multiplication and division with the powers of ten

So, when multiply powers of ten, all you have to do add up the powers.

The reverse goes when you are dividing. You would subtract the powers.

9 x 10^7                    =>   3 x 10^3

The words " how many times as large as " indicates that we are going to divide the two, making it look like this:

\frac{(9)(10^{7}) }{(3)(10^{3}) }

Divide the 9 by 3 you get 3

Then subtract 10^3 from 10^7

Therefore, the answer is 3 x 10^4, or A
