Facts about Pumice:
The lightest rock on earth.
Formed in Molten Lava.
Most of the earths crust is made from rocks such as Pumice (Igneous Rocks).
Contains many minerals that help plants to grow.
Facts about Sandstone:
It can form on land or in the sea.
It has been used as far back as prehistoric times to make house ware items and shelter contruction.

Answer:
Assuming that all of the oxygen is used up, 1.53×4111.53×411 or 0.556 moles of C2H3Br3 are required. Because there are only 0.286 moles of C2H3Br3 available, C2H3Br3 is the limiting reagent.
Limiting Reagent What is the limiting reagent if 76.4 grams of C2H3Br3 were reacted with 49.1 grams of O2? C2H3Br3 + 11O2 → 8CO2 + 6H2O + 6Br2 SOLUTION Using Approach 1: A. 76.4g × (1 mol/ 266.72 g) = 0.286 moles C2H3Br3 49.1g × (1 mole/ 32 g) = 1.53 moles O2 B.
