What mass of NaOH is contained in 2.5L
Of a 0.010M solution?
a 0.010g
B. 1.0g
c. 2.5g
D. 0.40g

B. 1.0g

Explanation:

Step 1

The molarity of the solution is 0.010 M, that is, there are 0.010 moles of sodium hydroxide per liter of solution. The moles of NaOH in 2.5 L of solution are:

Step 2

The molar mass of sodium hydroxide is 40.00 g/mol. The mass corresponding to 0.025 moles is:

There is 1.0 g of NaOH in the solution.

the answer is the

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
