1 x 1022 ym = 1 cm
1.296 grams = 0.001296kg
2068 grams
2.55 grams = 2,550 grams
Grams and grams are the same measurement. Therefore, 61.2 grams is equal to 61.2 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.
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.
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.
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.
2.50 grams C14H18N2O5 (1 mole C14H18N2O5/294.304 grams)(18 moles H/1 mole C14H18N2O5)(6.022 X 1023/1 mole H) = 9.21 X 1022 atoms of aspartame
Avogadro's Number is defined as the number of molecules in one gram atomic molecular mass of a substance and is known to have the approximate value of 6.022 X 1023. The gram molecular mass of water, with formula H2O, is 18.01528. Therefore, the number of water molecules in 1.805 grams of water is: (1.805/18.01528)(6.022)(1023) or 6.034 X 1022 molecules, to the justified number of significant digits.
To find the weight of 5.60 x 10^22 molecules of SiO2, you need to first calculate the molar mass of SiO2, which is 60.08 g/mol. Then, convert the number of molecules to moles using Avogadro's number. Finally, use the molar mass to find the weight in grams, which is approximately 3.37 x 10^5 grams.
25 grams / (17 grams/mole) x 6.022x1023 molecules/mole = 8.9x1023 molecules
