1. One mole of oxygen gas (O2) molecules has fewer atoms than one mole of ozone gas (O3) molecules ( True or false) 2. One molecule of oxygen gas (O2) has fewer atoms than one mole of ozone gas (O3) (True or false)
One molecule of ozone, O3, contains three oxygen atoms. Similarly, 1 mole of ozone contains 3 moles of oxygen atoms. We can use this mole ratio to create two conversion factors: 3 moles O1 mole O3 and 1 mole O33 moles O Here's how to find the number of moles of oxygen atoms in 2 moles of ozone: 2 moles O3×3 moles O1 mole O3= 6 moles O Part A Calculate the number of moles of aluminum, sulfur, and oxygen...
A) compound a contains 3.153 g of oxygen per gram of carbon whereas compound b contains 6.306 g of oxygen per gram of carbon what chemical law do these data illustrate? -law of constant compositoon -law of multiple proportions -law of concervation of mass B) if compound a has an equal number of oxygen and carbon atoms what can we conclude about thw composition of compound B? -it has 2x as many oxygen that carbon atoms -it has 1/2 as...
