How many grams are in 8.200 x 1022 molecules of N2I6?
The nitrogen iodide is NI3.
How many grams are in 8.2 x 10 to the 22 molecules of N2I6?
106.7 grams
How many atoms of silver in 10.8g?
10.8 grams silver (1 mole Ag/107.9 grams)(6.022 X 1023/1 mole Ag) = 6.03 X 1022 atoms of silver =====================
How many grams of N combine with 7.05x1022 O atoms in N2O5?
The formula N2O5 shows that there are 2/5 as many nitrogen atoms as oxygen atoms in the compound. Therefore, the number of nitrogen atoms required is (2/5)(7.05 X 1022) or 2.82 X 1022 atoms. The gram atomic mass of nitrogen is 14.0067 and, by definition, consists of Avogadro's Number of atoms. Therefore, the mass of nitrogen required to react with the specified amount of oxygen to produce the specified compound is 14.0067 [(2.82 X 1022)/(6.022 X 1023] or 0.656 grams of nitrogen, to the justified number of significant digits.
How many grams of lead is needed to equal the number of atoms contained in 10 grams of tin?
Let us do this in two parts for clarity. Find atoms in tin first. 10 grams tin (1 mole Sn/118.7 grams)(6.022 X 1023/1 mole Sn) = 5.07 X 1022 atoms of tin ----------------------------------- 5.07 X 1022 atoms (1 mole Pb/6.022 X 1023)(207.2 grams/1 mole Pb) = 17 grams of lead ------------------------------ I can see two other ways to do the conversion string, one longer and one much shorter. See if you can find them.
How many grams are in 8.200 x 1022 molecules of N2I6?
The nitrogen iodide is NI3.
How many grams are in 8.2x10to the 22 atoms of N2I6?
Quite a few! 8.2 X 10^22 atoms of N2I6 (1 mole N2I6/6.022 X 10^23)(789.42 grams/1 mole N2I6) = 107 grams of N2I6 (Would have been peanuts without all that iodine! )
How many atoms of gold are in 5 grams of gold?
Atomic mass of Ag: 107.9 grams5.00 grams × (6.02 × 1023 atoms) / (107.9 grams) = 2.79 × 1022 atoms Ag
How many atoms are in 1.9 g Carbon?
Atomic mass of carbon: 12.0 grams1.90 grams × (6.02 × 1023 atoms) / (12.0 grams) = 9.53 × 1022 atoms C
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 grams are in 8.2 x 10 to the 22 molecules of N2I6?
106.7 grams
How many atoms are in 2.13 grams of HBr?
2.13 g (6.02 x 1023 atoms) / (1.01 + 79.91) = 1.58 x 1022 atoms
How many grams are in 8.281023 molecules of N2l6?
107.5 g N2I6
How many atoms in 10 grams of lead?
10 grams lead (1 mole Pb/207.2 grams)(6.022 X 1023/1 mole Pb) = 2.9 X 1022 atoms of lead -----------------------------------
How many atoms of silver in 10.8g?
10.8 grams silver (1 mole Ag/107.9 grams)(6.022 X 1023/1 mole Ag) = 6.03 X 1022 atoms of silver =====================
How many grams are there in 3.3 x 1023 molecules of N2I6?
divide the amount of particles given in the question by avagado's number to get the amount in moles. 3.01 x 1023 / 6.022 x 1023 which is about 0.5 moles. them multiply the amount of moles by the mass of Nitrogen to get it in grams. 0.5 x 14 = 7g
How many na atoms can be produced Of 3.5g?
3.5 grams Na (1 mole Na/22.99 grams)(6.022 X 1023/1 mole Na) = 9.2 X 1022 atoms of sodium ===================
