In an experiment, zinc chlorite decomposed according to the following chemical equation. Zn(ClO3)2 -> ZnCl2 + O2. If the mass of zinc chlorite was 150 grams, which of the following calculations can be used to determine the mass of oxygen gas formed?

what is the average time it took the car to travel 0.25 meters?

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
