1. How many grams of solid NaCl (sodium chloride) is required to prepare 50ml of a 0.015M solution (fw=58.44g/mol 58). a. Show all the steps of your calculation

b. And how you will physically prepare this 50ml solution?

c. Express this solution in terms of g/L, and % w/v

d. If you prepare this salt at isotonic concentration with RBC (red blood cells at 0.154M), what will be the weight in grams of solid NaCl used for the same 50ml solution.

Solution;

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
