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.

The nitrogen iodide is NI3.
To calculate the number of grams in 4.1 x 10^22 molecules of N2I6, you first need to find the molar mass of N2I6. Then, use this molar mass to convert the number of molecules to grams using Avogadro's number and the formula: grams = (number of molecules) / (Avogadro's number) * molar mass.
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).
147 (g) SiO2 / 60.1 (g/mol) = 2.446 mol SiO2(the molar mass of SiO2 is 60.1 g/mol)
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 )
To find the grams of nitrogen dioxide needed, first calculate the moles of nitrogen monoxide using Avogadro's number. Then, use the balanced chemical equation to determine the moles of nitrogen dioxide required. Finally, convert moles to grams using the molar mass of nitrogen dioxide.
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
The first step is calculating how many molecules of glucose are in 3.00 grams. To do this, you need the molecular mass of the compound (glucose), which is found by adding up the weights of the elements involved in C6H12O6. C6: 12.0 × 6 = 72.0 H12: 1.0 × 12 = 12.0 O6: 16.0 × 6 = 96.0 72.0 + 12.0 + 96.0 = 180.0 grams/mol With this and Avogadro's constant (6.02 × 1023), we can then convert 3.00 grams of glucose to number of molecules. 3.00 grams ÷ 180.0 grams/mol × (6.02 × 1023) = 1.00 × 1022 molecules of glucose So now we know how many molecules of glucose there are. We also know from the formula that in one molecule of glucose, there are 6 atoms of carbon, 12 atoms of hydrogen, and 6 atoms of oxygen. Number of atoms in one molecule × number of molecules = number of atoms in given amount 6 × (1.00 × 1022) = 6.00 × 1022 atoms of carbon 12 × (1.00 × 1022) = 1.20 × 1023 atoms of hydrogen 6 × (1.00 × 1022) = 6.00 × 1022 atoms of oxygen

The mass is 2.86 grams but the weight will be 0.028 Newtons.
To convert molecules to grams, first find the molar mass of NCl3: Nitrogen (N) has a molar mass of 14.01 g/mol, and chlorine (Cl) has a molar mass of 35.45 g/mol. Therefore, the molar mass of NCl3 is 14.01 + (3 * 35.45) = 120.36 g/mol. Now, use this molar mass to convert molecules to grams: 8.2 x 10^22 molecules * (1 mol / 6.022 x 10^23 molecules) * 120.36 g/mol ≈ 16.06 grams.
