How many nitrogen atoms are present in calcium nitrate? How many atoms does glucose have? How many molecules are there in 0.56g of CO2? What is the formula for ammonium bicarbonate? What are the four elements found in ammonium carbonate? How many atoms are in one molecule of Na2SO4? How...
The relative number of moles of elements in a compound is called the mole ratio, which gives an idea of the composition of a compound. However, the mole ratio of a compound does not necessarily represent how many moles there are of each element in the compound....
