Answer:
1.06 M
Explanation:
Lets answer this question using the definition for molarity of a solution, M.
M = mol of solute/ Volume of solution in L
We are adding more moles of NaOH to a solution which is already 2.40, so the final number of moles are
25 g x 1 mol / 40 g/mol = 0.625 mol
mol NaOH in 1.5 L of 2.40 M NaOH:
1.5 L x 2.40 mol/L = 3.6 mol
Total # mol = 0.625 mol + 3.6 mol = 4.23 mol
The final volume is 4.00 L so the new molarity is:
M = 4.23 mol / 4 L = 1.06 M

Answer:
The Boiling Point would be below a hundred degrees on a mountain than at sea level.
Explanation:
The Boiling Point is below a hundred degrees, because the air pressure at high altitudes is very low. ( -- < 100)
The Boiling Point for at sea-level would-be a hundred degrees because the air pressure is very high at lower altitudes.
First Model: is shown below, and it shows that the motion of thermal energy particles are moving fast when<u> below 100</u> degrees ( -- < 100).
Second Model: is shown below, and it shows that the motion of thermal energy are moving fast when <u>at 100</u> degrees (--- = 100)
Hope this helps!
