The concentration of a solution can be changed by adding solute. More solute=more concentrated
Answer:
Yes; the graph shows a strong positive linear association.
Explanation:
Majority of the points outline a line of the graph. There are only a few outliers.
Explanation:
a) 3 sig. figures
b) 3 sig. figures
c) 6 sig. figures
d) 2 sig. figures
e) 1.09 × 104 = 113.36 = 5 sig. figures
if it is 1.09 × 10^4, it is 10900 = 3 sig. figures
f) 4 sig. figures
The amount of Al that would be needed will be 0.79 grams
<h3>Stoichiometric calculations</h3>
From the equation of the reaction below:

The mole ratio of Al to
is 2:3.
Mole of 71.8 mL. 0.610 M
= 0.610 x 71.8/1000 = 0.0438 moles
Equivalent mole of Al = 2/3 x 0.0438 = 0.029 moles
Mass of o.o29 moles Al = 0.029 x 26.98 = 0.79 grams
