while studying exothermic reactions, laura and her lab partner are instructed to add magnesium to hydrochloric acid. based on their math, the theoretical yield of magnesium chloride is 10.75 grams. they measured the mass of magnesium chloride at the conclusion of the reaction and found that 10.31 were produced. what is the percent yield?

a)104%
b)96%
c)91%
d)88%

Option B. 96%

Explanation:

To find out the percent yield, let's make a percent:

( Total produced / Theoretical yield )  . 100

(10.31 g / 10.75 g)  . 100 = 96 %

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
