How many grams are in 1.50 moles of SiOz?

90.126g

Explanation:

I am going to assume that the equation is supposed to say SiO2.

We want to calculate the number of grams in 1.50 moles of SiO2.

First we must find the molecular mass of SiO2

Looking at a periodic table, the mass of Silicon(Si) is 28.086g and the mass of Oxygen(O) is 15.999g

Using this, the mass of SiO2 would be 28.086 + 15.999(2) = 60.084g

Now we can use dimensional analysis to find the number of grams in 1.50 moles of SiO2

The table created should look something like

the molSiO2 cancel out and we get

= 90.126g

So there are 90.126g of SiO2 in 2 moles of SiO2

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
