How many molecules of water can be produced by the reaction of 2.16 mol of oxygen with excess Ethylene.?
C2H4 + 3 O2 --> 2 CO2 + 2 H2OSo 2.16 mol O2 will produce 1.44 mol H2O(and 1.44 mol CO2)because 3:2 = 2.16 : 1.44
How many molecules are present in 347g of CaCl 2?
To find the number of molecules in 347 grams of CaCl₂, first calculate the molar mass of CaCl₂, which is approximately 110.98 g/mol (40.08 g/mol for Ca and 35.45 g/mol for each Cl atom). Then, divide the mass by the molar mass: 347 g ÷ 110.98 g/mol ≈ 3.13 moles. Finally, multiply the number of moles by Avogadro's number (approximately 6.022 x 10²³ molecules/mol): 3.13 moles × 6.022 x 10²³ molecules/mol ≈ 1.89 x 10²⁴ molecules.
How many moles of CO2 will be produced from 0.33 mol C3H8O in the reaction 2C3H8O plus 9O2 producing 6CO2 and 8H2O?
Given the balanced equation2C3H8O + 9O2 --> 6CO2 + 8H2OTo find the number of moles CO2 that will be produced from 0.33 mol C3H8O, we must convert from moles to moles (mol --> mol conversion).0.33 mol C3H8O * 6 molecules CO2 = 0.99 mol CO2---------- 2 molecules C3H8O
How many molecules are there in 2 grams of hydrogen gas?
To calculate the number of molecules in 2 grams of hydrogen gas, you first need to determine the number of moles of hydrogen using the molar mass of hydrogen (2 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How many molecules of O2 will be required to produce 1.60 mol of water?
To produce water (H₂O), the balanced chemical equation is 2 H₂ + O₂ → 2 H₂O. From this equation, we see that 1 mole of O₂ produces 2 moles of H₂O. Therefore, to produce 1.60 moles of water, you would need 0.80 moles of O₂ (1.60 mol H₂O × 1 mol O₂ / 2 mol H₂O = 0.80 mol O₂).
How many many water molecules are in a drop of water?
The reactants of water H (2) + O (2) exist as diatomic molecules only. Therefore, 1 mol of Hydrogen + 1 mol of Oxygen will give 2H(2)O (or 2 mols of Water). Water always exists as a diatomic molecule as well, and this is why it will always have 2 molecules as the most basic possible ratio.

How many molecules of oxygen are produced when a sample of 29.2 g of water is decomposed by electrolysis?
The molar mass of water is 18 g/mol, so 29.2 g is equivalent to 1.62 mol of water. Through electrolysis, each water molecule decomposes into 1 molecule of oxygen and 2 molecules of hydrogen. Therefore, 1.62 mol of water will produce 1.62 mol of oxygen molecules, which is equivalent to 9.73 x 10^23 molecules of oxygen.
How many molecules of H2(g) are there in a 21.25 gram sample?
To calculate the number of molecules, you first need to determine the number of moles of H2 in the 21.25 gram sample using the molar mass of H2 (2 grams/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.

How many molecules are there in 450 grams of NaSO4?
To find the number of molecules in 450 grams of NaSO4, we first need to calculate the number of moles using the molar mass of NaSO4 (142.04 g/mol). Then, we can use Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of molecules in the calculated moles.
How many atoms of H are in 2 mol of c8h18?
To determine the number of hydrogen atoms in 2 mol of C8H18, we first need to calculate the molar mass of C8H18. Carbon has a molar mass of approximately 12 g/mol, and hydrogen has a molar mass of approximately 1 g/mol. Therefore, the molar mass of C8H18 is (812) + (181) = 114 g/mol. Next, we use Avogadro's number (6.022 x 10^23) to calculate the number of molecules in 2 mol of C8H18, which is 2 mol * 6.022 x 10^23 molecules/mol. Since there are 18 hydrogen atoms in each molecule of C8H18, the total number of hydrogen atoms in 2 mol of C8H18 is 2 mol * 6.022 x 10^23 molecules/mol * 18 atoms/molecule = 2.17 x 10^25 hydrogen atoms.
