The first step to finding the molar mass of Potassium Chlorate is to count the number of each atom present in a single molecule using the chemical formula, K(ClO3): ElementNumber of Atoms K (Potassium) 1 Cl (Chlorine) 1 O (Oxygen) 3 2. Find Atomic Mass of Each Element Next, using...
How many grams of potassium chlorate decompose to form potassium chloride and 250.0 mL of 02 at 127C and 0.850 atm of oxygen? What is the molar mass of calcium hydroxide? What is the molar mass of N2O4? What is the molar mass of (NH4)2CO3? What is the molar mass of sodium carbonat...
carbon monoxide has positive and adverse effects on humans. increased levels of carbon monoxide in red blood cells decrease the amount of oxygen haemoglobin carries throughout the body. the effect is that vital organs like the brain, nervous tissues, and the heart don’t get enough oxygen to ...
