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 grams of nitrogen dioxide must react with water to produce 5.00 x 1022 molecules of nitrogen monoxide?
How many oxygen atoms are in 3.30 of quartz?
3.30 gSiO2 / 60.085g SiO2 x 2 mol 0 / 1 mol SiO2 x (6.022*1023 )= 6.61*1022 O atoms
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 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 grams are in 8.2 x 1022 molecules of NCl3?
1 mole NCl3 = 120.366g NCl3 = 6.022 x 1023 molecules NCl3 8.2 x 1022 molecules NCl3 x 120.366g NCl3/6.022 x 1023 molecules NCl3 = 16g NCl3 rounded to 2 significant figures

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 the number of carbon hydrogen and oxygen atoms in 3.00 grams of glucose?
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
