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.
How many grams of nitrogen are there in 7.5g of Ca NO3 2?
There are 2.76 grams of nitrogen in 7.5g of Ca(NO3)2.
How many grams of Cu(NO3)2 will be produced if you start with 4.2 grams of cu?
To determine the number of grams of Cu(NO3)2 produced, you need to consider the molar ratio between Cu(NO3)2 and Cu. Firstly, convert the 4.2 grams of Cu to moles using the molar mass of Cu. Then, use the balanced chemical equation to find the moles of Cu(NO3)2 produced. Finally, convert the moles of Cu(NO3)2 to grams using its molar mass.

How many moles in 13.5 grams of magnesium nitrate?
To find the number of moles in 13.5 grams of magnesium nitrate, you need to divide the given mass by the molar mass of magnesium nitrate. The molar mass of magnesium nitrate (Mg(NO3)2) is 148.31 g/mol. Moles of magnesium nitrate = 13.5 grams / 148.31 g/mol ≈ 0.091 moles
How do you Convert 8.50 grams HgNO32 to moles?
For this you need the atomic (molecular) mass of Hg(NO3)2. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. Hg(NO3)2=324.6 grams8.50 grams Hg(NO3)2 / (324.6 grams) = .0262 moles Hg(NO3)2

Marie and Calvin tried dissolved 45 grams of NO3 in 100 grams of water at 25oC Five grams of solute settled out so they heated the water to 55oC and they were able to dissolve the extra 5 grams of so?
Increasing the temperature of the solution allowed more of the solute (NO3) to dissolve due to an increase in solubility. As temperature increases, the kinetic energy of the solvent molecules also increases, making it easier for the solute molecules to break apart and dissolve. At 55°C, the solubility of the compound was high enough to dissolve the extra 5 grams that initially settled out at 25°C.
How many grams of CrNO33 are required to prepare 500.0 mL of an aqueous solution which has a Cr3 concentration of 2.08 M?
To determine the grams of Cr(NO3)3 needed, first calculate the molar mass of Cr(NO3)3. Then, use the formula: moles = Molarity x Volume (in L) to find the moles of Cr(NO3)3. Finally, multiply the moles by the molar mass to get the grams.
