How many moles of sodium oxide will be produced with 10 moles of sodium react with oxygen?
1 mole of Sodium Chloride weighs 58.5 grams (1 mole is the same as the molecular weight of a compound. The molecular mass of Sodium Chloride- NaCl is 23 [Na atomic mass] + 35.5 [Cl atomic mass] which is equal to 58.5 grams).Thus 10 moles would weigh 10x58.5 grams = 585 grams.The answer is 585 grams.
How many grams of oxygen wil be in two moles of potassium dichromate?
In potassium dichromate (K2Cr2O7), there are 7 oxygen atoms per molecule. Therefore, two moles of K2Cr2O7 would contain 14 moles of oxygen atoms. Each mole of oxygen atoms has a molar mass of approximately 16 grams, so there would be 224 grams of oxygen in two moles of potassium dichromate.
How many moles are in 119 grams of uranium?
To find the number of moles in 119 grams of uranium, you need to divide the given mass by the molar mass of uranium. The molar mass of uranium is approximately 238.03 grams/mol. Dividing 119 grams by 238.03 grams/mol gives you 0.5 moles of uranium.
How many atoms does thirty two grams of sulfur contain?
Thirty two grams of sulfur contains approximately 1.0 x 10^23 sulfur atoms. This is calculated by converting the mass to moles and then using Avogadro's number to determine the number of atoms in that many moles.
What mass of oxygen two moles of O2 molecules have molor mass of O2 is 32 grms per mole?
Two moles of O2 molecules would have a mass of 64 grams (2 moles x 32 grams/mole = 64 grams).
How do you make 2 molarity solution of NaCl?
Two moles of sodium chloride is equivalent to 116,88 (rounded) g.The molar mass of NaCl 58.5 grams per mole. 117 grams of salt is equivalent to two moles. Dissolve this much of salt in exactly 1L of distilled water in a volumetric flask to prepare 2M NaCl.
How many grams of salt must be dissolved in water to make two liters of a two mole salt solution?
To make a two mole salt solution in two liters of water, you'll need 4 moles of salt (2 moles/L * 2 L = 4 moles). The molar mass of salt (NaCl) is approximately 58.44 g/mol, so 4 moles would be 233.76 grams (4 moles * 58.44 g/mol = 233.76 g).
How many moles of sodium oxide will be produced with 10 moles of sodium react with oxygen?
1 mole of Sodium Chloride weighs 58.5 grams (1 mole is the same as the molecular weight of a compound.

How many moles are in 13g NaCl?
For this conversion you need the atomic masses of the two elements to find the molecular mass of the NaCl.Na: 23.0Cl: 35.5NaCl: 58.5Then, you follow the formula:Mass in grams ÷ Molecular mass = Mass in moles1000 g NaCl ÷ 58.5 = 17.1 moles NaCl
How many moles per mL of the solute are contained in the 0.20 M NaCl?
0.0002 mol NaCl/mLmolarity = (moles solute)/(L of solution)0.20 M NaCl = 0.20 mol NaCl/L1 L = 1000 mL0.20 mole NaCl/1000 mL = 0.00020 mol NaCl/mL (rounded to two significant figures)
How many moles are in 64 g of oxygen?
