How many Cu atoms are present in 85mol?
To calculate the number of Cu atoms in 85 mol, you need to use Avogadro's number, which is approximately 6.022 x 10^23 atoms/mol. So, for 85 mol of Cu, the number of Cu atoms would be 85 mol x 6.022 x 10^23 atoms/mol = 5.12 x 10^25 Cu atoms.
How many moles of nitrogen N are in 60.0 g of nitrous oxide N2O?
For this you need the atomic (molecular) mass of NaNO3. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaNO3=85.0 grams60.1 grams NaNO3 / (85.0 grams) = .707 moles NaNO3
If 4.25 g of NaNO3 (molar mass 85 gmole) are dissolved in 100 mL of H2O. What is the molarity of the resulting solution?
4.25 g NaNO3 x 1 mole NaNO3/85 g = 0.05 moles0.05 moles/0.1 L = 0.5 moles/L = 0.5 M
How many in are there in 85 in?
There are 85 inches in 85 inches.
What is the molality of a solution mabe by combining 20.0 of nano3 with 750.0 g of water?
To calculate the molality of the solution, we first need to determine the number of moles of NaNO3. The molar mass of NaNO3 is approximately 85 g/mol, so 20.0 g of NaNO3 corresponds to about 0.235 moles (20.0 g / 85 g/mol). Molality (m) is defined as the number of moles of solute per kilogram of solvent. With 750.0 g of water (0.750 kg), the molality is 0.235 moles / 0.750 kg = 0.313 m.
What is the mass ofCO2 if you have 85g of oxygen?
85g of oxygen = 85/16 moles of O atoms = 5.3125 moles There are 2 moles of oxygen atoms per mole of carbon dioxide, so we have 2.65625 moles of carbon dioxide. This is 2.65625 x 44 g = 116.875 g.
How many moles of AgNO3 does 85 grams of AgNO3 represents?
To find the number of moles, you need to divide the given mass (85 grams) by the molar mass of AgNO3 (169.87 g/mol). 85 grams of AgNO3 represents 0.500 moles.

How many MOLES of sodium nitrate are present in 2.85 grams of this compound?
To find the number of moles, first calculate the molar mass of sodium nitrate (NaNO3), which is 85 grams/mol. Then, divide the given mass (2.85 grams) by the molar mass to obtain the number of moles present, which is approximately 0.0335 moles.
How many moles of H3O are present in an 85 L solution with a pH of 3.0?
To find the number of moles of H3O in the solution, you can use the formula pH -logH3O. First, calculate the concentration of H3O ions using the pH value: pH -logH3O 3.0 -logH3O H3O 10(-3.0) 1.0 x 10(-3) M Next, calculate the number of moles of H3O in the solution using the concentration and volume: moles concentration x volume moles 1.0 x 10(-3) mol/L x 85 L moles 8.5 x 10(-2) moles Therefore, there are 8.5 x 10(-2) moles of H3O present in the 85 L solution with a pH of 3.0.

If an atoms mass number is 210 and its atomic number is 85. how many nuetrons does it have?
To find the number of neutrons in an atom, you subtract the atomic number from the mass number. In this case, the mass number is 210 and the atomic number is 85. Therefore, the number of neutrons is 210 - 85 = 125. Thus, the atom has 125 neutrons.
