The density of the gas is 1.45 g/L.
The mass of the gas is 0.0707 g.
The volume of the gas is 48.9 mL.
Density = mass/volume = 0.0707 g/48.9 mL = 1.45 × 10⁻³ g/mL = 1.45 g/L
Answer: It is C I just did this question in math class
Explanation:
The correct answer is B. The concentration of a solution does not decreases when you add more solute to the solvent. Instead, the concentration increases. Concentration is expressed as the amount of solute per unit of solvent. Therefore, increasing the solute, increases this value and increasing the solvent, decreases this value.
Answer:
Mechanical Energy to Thermal Energy
When you strike a match, it moves through the air until it rubs against a surface. The rubbing produces the heat required to light the match. This is a transformation from mechanical energy to thermal (heat) energy.
