Explanation:
Im not to sure about 1. but other than that your good sorry if this didn't help
The correct answer is D. Salt water.
Explanation
The hydrosphere is the system that groups all the waters of the earth that include oceans, seas, rivers, lakes, lagoons, frozen waters like ice and snow, among others. The water of the earth can be classified between salt water and freshwater, within the first group we find the oceans and the seas that represent two thirds of the total water of the earth, that is, 93 percent of the total water of the earth, a figure close to 1 370 323 000km³; the rest of the water is fresh and consists of rivers, lakes, lagoons, streams, groundwater, and glaciers. So, the correct answer is D. Salt water
Explanation:
The given data is as follows.
= 3 M, 
= ?
= 10 M, 
= 10.0 ml
Therefore, calculate the volume of given solution as follows.
= 
Now, putting the given values into the above formula as follows.
=
= 
= 33.3 ml
or, = 0.033 L (as 1 ml = 0.001 L)
Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml.
Molarity = 
3 M = 
mass = 3.96 g
Therefore, we can conclude that mass of NaOH is 3.96 g.
