Answer: The molarity of the borax solution is 0.107 M
Explanation:
The neutralization reaction is:
According to neutralization law:
where,
= basicity of
= 2
= acidity of borax = 2
= concentration of
= 1.03 M
= concentration of borax =?
= volume of
= 2.07ml
= volume of borax = 20.0 ml
Now put all the given values in the above law, we get the molarity of borax:
By solving the terms, we get :
Thus the molarity of the borax solution is 0.107 M
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.
