How many oxygen atoms are in 2.60g of quartz?
This is a complex tetrahedral formula, but SiO2 is the accepted formula for our purposes. I assume you mean 1.40 grams quartz. 1.40 grams SiO2 (1 mole SiO2/60.09 grams)(2 mole O/1 mole SiO2)(6.022 X 10^23/1 mole O) = 2.81 X 10^22 atoms of oxygen ( may need the tetrahedral formulation. In this form the O2 is shared and the form is SiO4. So, same ratios, different numbers. SiO2 is standard though )
How many oxygen atoms are in 3.80 g of quartz?
Ans:Quartz is SiO2. It has a formula weight of 60.1 g/mol. 3 grams of SiO2 is 0.05 moles.Each mole of SiO2 has 0.1 moles of oxygen since there are 2 oxygen atoms per formula unit of SiO2.(1 mole of anything is 6.02x1023 of anything.)0.1 mol oxygen atoms x 6.02x1023 oxygen atoms / mol oxygen atoms= 6.02 x 1022 oxygen atoms.Number of O atoms =6.02×1022
How many moles are there in 5 grams of silicon dioxide?
To determine the number of moles in 5 grams of silicon dioxide (SiO2), you first need to calculate the molar mass of SiO2. The molar mass of SiO2 is 60.08 g/mol. Then, use the formula Moles = Mass / Molar mass to find that there are approximately 0.083 moles in 5 grams of SiO2.
How do you determine the number of silicon atoms in 4SiO2?
4SiO2 means SiO2 + SiO2 + SiO2 + SiO2 The '4 'tells you that there are four seprate molecules of SiO2 So there will be 4 silicon atoms in 4SiO2 SiO2 also contains 2 oxygen atoms. So overall there will be 4 x 2 = 8 oxygen atoms. SiO2 is silicon dioxide ; sand that you find on a beach. It does form large crystal lattice by a loose combination through the oxygen atoms.
How many oxygen atoms are in 1.00 g of quartz?
The chemical composition of quartz is Silicon Dioxide, or SiO2. From the molar mass of quartz, 1.60 grams = 26.6 millimols. There are two moles of oxygen for every mol of SiO2, so there are 53.2 millimols of oxygen present. Given Avogadro's number (6.022 E 23), the result is 3.204 E22 atoms of oxygen.
How many grams does 5.60 x 1022 molecules of SiO2?
To find the mass, we divide by Avogadro's number to find the amount of moles. We then multiply the moles by the molar mass of the compound which is 60.08 grams. Doing all of this, we get a mass in grams of 5.59 grams.

How many oxygen atoms are in 3.30 of quartz?
Quartz is represented by the chemical formula SiO2, which means each molecule of quartz contains one oxygen atom. To calculate the number of oxygen atoms in 3.30 g of quartz, you would need to convert grams to moles of SiO2 (60.08 g/mol) and then use the mole ratio of SiO2 to oxygen to find the number of oxygen atoms. The total number of oxygen atoms in 3.30 g of quartz can be calculated as follows: 3.30 g SiO2 * (1 mole SiO2 / 60.08 g SiO2) * (2 moles O / 1 mole SiO2) * (6.022 x 10^23 atoms / 1 mole O).

How many moles are in 147 grams of SiO2?
147 (g) SiO2 / 60.1 (g/mol) = 2.446 mol SiO2(the molar mass of SiO2 is 60.1 g/mol)

What is chemical equation for sand?
The chemical equation for sand is SiO2, which represents silicon dioxide. Sand is primarily composed of silicon dioxide molecules arranged in a crystalline structure.
How much of SiO2 would you start with to prepare 0.30kg of glass?
To prepare 0.30 kg of glass, you would need to start with at least 0.30 kg of SiO2 because silica (SiO2) is one of the main components of glass. Keep in mind that the actual amount of SiO2 required might be slightly higher to account for losses during the glass-making process.
what are the types of covalent bonding that we have?
Discrete covalent molecules. eg CO2, N2,CH4. Covalent networks. eg SIO2
How many grams of sand are needed to make 45 grams of silicon?
To make silicon from sand, you would need to extract the silicon dioxide (SiO2) from the sand. The atomic mass of silicon dioxide is 60 grams/mole. Since the molar ratio of silicon to silicon dioxide is 1:1, you would need 45 grams of sand to obtain 15 grams of silicon (45 grams x 1 mol Si/60 g SiO2).
