The mass of the object is the sum of the masses which shows the riders:
m = 300.00 g + 20.00 g + 8.00 g
m = 328.00 g
Answer:
The mass of the object is 328.00 grams.

Answer:
The correct answer is C) 1 L of 1.0 M NaCl
Explanation:
NaCl is a ionic compound so it dissociates in water into Na⁺ and Cl⁻ ions. Glucose is a covalent solute so it does not dissociates into ions. So, when we dissolve NaCl we have twice the amount of particles in solution in comparison with glucose. According to this:
A) and B) are solutions with the same concentration (0.5 M) but NaCl solution will have more solute particles than glucose.
C) and D) are solutions with more solute amount because they are more concentrated (1 M), but NaCl solution will have more solute particles than glucose solution ( 1 mol of Na⁺ ions + 1 mol of Cl⁻ ions).
The solution with the greatest solute particle number is C).
Answer:
Reflected ray
Explanation:
The angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface is the angle of reflection.
