The basic steps of the scientific method are: 1) make an observation that describes a problem, 2) create a hypothesis, 3) test the hypothesis, and 4) draw conclusions and refine the hypothesis. ... Critical thinking is a key component of the scientific method. Without it, you cannot use logic to come to conclusions.
Explanation believe the answer is A. Average.
The density of water at 20 °C is 0.9982 g/cm^{3} or 998.2 g/L. The volume of water is 0.127 L thus, its mass can be calculated from the following formula:
d=\frac{m}{V}
Here, d is density, m is mass and V is volume of water.
On rearranging,
m=d×V=(998.2 g/L)(0.127 L)=126.7 g
Thus, mass of water is 126.7 g.
