Answer:
Yes
Explanation:
First remember that a significant figure are basically values that contribute to the precision of a value. In any scientific notation the values are significant figures because these values stay the same. In this case we have two significant figures which is 6 and 0, you can further prove that they are significant figures by converting the notation into standard form.
Negative so move the decimal point to the left:
6 and 0 are the significant figures in this standard notation because it's precise to it's actual value which is 6.0.
To sum up, the values you have on the left side of a notation are significant figures since they will not change no matter if it's standard or scientific notation meaning it's precise.
Hope this helps.
Answer: There are 20.24 grams of in the solution if the molarity is 0.649 M.
Explanation:
Molarity equals number of moles in a liter of solution as follows.
and,
Therefore,
Now, putting values in the above formula as follows.
(convert the volume from milliliter to liter)
Thus, there are 20.24 grams of in the solution if the molarity is 0.649 M.
