How many yoctometers are in a centimeter?
1 x 1022 ym = 1 cm
How many kilo grams are in 1.296 grams?
1.296 grams = 0.001296kg
How many grams are there in 2 kg and 68 grams?
2068 grams
How many milligrams is 2.55 grams?
2.55 grams = 2,550 grams
How many grams equals 61.2 grams?
Grams and grams are the same measurement. Therefore, 61.2 grams is equal to 61.2 grams.
How many grams are in 8.200 x 1022 molecules of N2I6?
The nitrogen iodide is NI3.
How many grams of nitrogen dioxide must react with water to produce 5.00 x 1022 molecules of nitrogen monoxide?
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.
How many grams are in 8.2 x 1022 molecules of NCl3?
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.
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 atoms are there in 1.3 x 1022 molecules of NO2?
To find the number of atoms in 1.3 x 10^22 molecules of NO2, we need to consider the number of atoms in each molecule. NO2 has 3 atoms (1 nitrogen and 2 oxygen). So, the total number of atoms in 1.3 x 10^22 molecules of NO2 would be 3.9 x 10^22 atoms.
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
How many molecules are contained in a 6.95 g sample of dimethylmercury?
1.814*1022
How many grams do 4.4 x 1022 atoms of potassium weigh. answer in units of grams?
The mass is 2.86 grams but the weight will be 0.028 Newtons.
How many molecules of aspartame are present in 4.50 of aspartame?
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
How many water molecules are in 1.805 grams of water?
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.
How many atoms does 2 grams of BeCl2 have?
2 grams of BeCl2 corresponds to one mole of BeCl2, which contains 1 Be atom and 2 Cl atoms per molecule. So, there will be 1 Be atom and 2 Cl atoms, totaling 3 atoms in total.
How many grams does 5.60 x 1022 molecules of SiO2 weigh?
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.
