How many molecules are there in 122 grams of Cu NO3 2?
To determine the number of molecules in 122 grams of Cu(NO3)2, you need to first calculate the number of moles of Cu(NO3)2 using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23) to convert the moles of Cu(NO3)2 to molecules.
How many molecules are there in 122 grams of Cu(NO3)2?
To find the number of molecules in 122 grams of Cu(NO3)2, we need to first calculate the molar mass of Cu(NO3)2. The molar mass of Cu(NO3)2 is approximately 187.55 g/mol. Next, we convert the given mass to moles using the molar mass. Finally, we use Avogadro's number (6.022 x 10^23) to find the number of molecules, which would be approximately 3.25 x 10^22 molecules.
What is the total mass of NH4Br that must be dissolved in 200 grams of H20 at 60C to produce a saturated solution?
The solubility of NH4Br in water at 60°C is 122 g/100g H2O. To produce a saturated solution, the mass of NH4Br that must be dissolved in 200g of water can be calculated using this ratio. Therefore, the total mass of NH4Br needed would be (122/100) x 200 = 244 grams.
What is the theoretical yield of aluminum oxide if 2.40 mole of aluminum metal is exposed to 2.10 mol of oxygen?
To determine the theoretical yield of aluminum oxide, we first need to write a balanced chemical equation for the reaction between aluminum and oxygen to form aluminum oxide. The balanced equation is 4Al + 3O2 -> 2Al2O3. From the equation, we can see that 4 moles of aluminum react with 3 moles of oxygen to produce 2 moles of aluminum oxide. Therefore, if 2.40 moles of aluminum is exposed to 2.10 moles of oxygen, the limiting reactant is oxygen. Using stoichiometry, we can calculate the theoretical yield of aluminum oxide, which is 1.60 moles.
How many dozens of copper atoms in a penny?
A US 1 cent piece prior to 1982 was made of copper and had a mass of about 3.1g. This is about 0.049 moles of copper, or around 2.9 x 1022 atoms. More recent pennies are mostly zinc (97.5%) and have a mass of about 2.5g. This works out to around 2.2 x 1022 zinc atoms and 5.9 x 1020 copper atoms, so overall around 2.3 x 1022 atoms.
How many milligrams in 122 grams?
122 grams is 122,000 milligrams.
How many moles of atoms are in 500.00 mg of calcium?
Calcium hydroxide (Ca(OH)2) has a molar mass of 74g/mol. To find the number of moles in 0.5000g of calcium hydroxide, you divide the 0.5000gCa(OH)2 by 74gCa(OH)2. The answer is 0.006757mol Ca(OH)2 to the nearest significant figure.
