Explanation:
For Mg, (1.2 g Mg/24 g Mg) = 0.05 mol Mg.
For Cl, (3.55 g Cl/35.5 g Cl) = 0.1 mol Cl
So the ratio now is
Mg:Cl = 0.05 : 0.1 = 1:2
I got the 1:2 ratio by dividing both by the smallest number, which is 0.05 mol. Therefore, the empirical for formula of the substance is 
Answer:
If a gas has experienced a small increase in volume but has maintained the same pressure and number of moles, the temperature of the gas will DROP.
Explanation:
According to Boyle’s law of ideal gases, volume and temperature of a gas is inversely related, as long as the pressure is kept constant;
P₁V₁/T₁ = P₂V₂/T₂
Therefore, if the volume of the gas increases, the temperature will definitely decrease due to the inverse relationship. The gas will get cooler.

Answer:
a. 0.191 ppm b. 4.962 ppm c. 0.0385 ppm
Explanation:
a. 17 g of calcium = 0.017 mg. 89 mL = 0.089 L.
So our concentration = 0.017 mg/0.089 L = 0.191 mg/L = 0.191 ppm
b. 0.65 mg of caffeine in 131 mL = 0.131 L.
So our concentration = 0.65 mg/0.131 L = 4.962 mg/L = 4.962 ppm
c. 0.35 mg of trace particle in 91 dL = 9.1 L.
So our concentration = 0.35 mg/9.1 L = 0.0385 mg/L = 0.0385 ppm
