I mole of copper hydroxide is 98g (64 + 16 + 1 + 16 + 1)
So 68g is 68/98 moles
= 0.694g
I have used 64 for the ram of copper. Your list might use a slightly different value, so substitute that.

∙ 7y agomolar mass of copper(II) hydroxide, Cu(OH)2 is 97.6 g/mole. Thus...
68 g x 1 mol/97.6 g = 0.696 = 0.70 moles (2 significant figures).

If you have 60 grams of sodium hydroxide NaOH (FW 40 gramsmole) how many moles of sodium hydroxide would you have?
You would have 1.5 moles of sodium hydroxide. This is calculated by dividing the mass of sodium hydroxide by its molar mass: 60 grams / 40 grams/mole = 1.5 moles.
How many moles of atoms are in 4.5 grams of Cu?
4,5 moles of copper are equivalent to 285,957 g.
How many grams of sodium hydroxide are present in 675 mL of a 0.500M solution?
To calculate the grams of sodium hydroxide present in the solution, first calculate the number of moles using the formula: moles = Molarity (M) x Volume (L). Then, use the molar mass of sodium hydroxide (NaOH) to convert moles to grams. The molar mass of NaOH is 40 g/mol. Thus, in this case, you have 0.3375 moles of NaOH and if you convert this to grams, it would be 13.5 grams.
How many moles are there in 37 grams of calcium hydroxide?
To find the number of moles in 37 grams of calcium hydroxide, you need to divide the given mass by the molar mass of calcium hydroxide. The molar mass of calcium hydroxide (Ca(OH)2) is 74.1 g/mol. Therefore, 37 grams of calcium hydroxide is equal to 0.499 moles.
How many moles of sodium hydroxide are in 40 grams of sodium hydroxide?
To find the number of moles in 40 grams of sodium hydroxide, you first need to calculate the molar mass of NaOH. The molar mass of NaOH is about 40 g/mol. Then, you divide the given mass by the molar mass to get the number of moles. So, 40 grams divided by 40 g/mol is equal to 1 mole of NaOH.
How many grams of sodium hydroxide (NaOH) are there in 0.150 mol?
To determine the grams of sodium hydroxide in 0.150 mol, you need to use the molar mass of NaOH, which is 40.00 g/mol (Na = 22.99 g/mol, O = 16.00 g/mol, H = 1.01 g/mol). 0.150 mol NaOH x 40.00 g/mol = 6.00 grams of NaOH.
How many grams of copper will react to completely replace silver from 666mL of a 1.5M solution of silver nitrate?
To completely replace silver in the solution with copper, you would need an equal number of moles of copper to the moles of silver present. Calculate the moles of silver in the solution using the concentration and volume given. Then use the mole ratio between copper and silver to determine the moles of copper needed, and convert this to grams.
How many grams of boric acid would be needed to neutralize 35 grams of calcium hydroxide?
To neutralize calcium hydroxide, the molar ratio is 2:1 (2 moles of boric acid for every 1 mole of calcium hydroxide). Calculate the molar mass of boric acid (H3BO3) and calcium hydroxide (Ca(OH)2), then use these values to convert the mass of calcium hydroxide to moles and then to grams of boric acid.
How many grams of sodium hydroxide are there in 0.150 mol?
To find the grams of sodium hydroxide in 0.150 mol, first calculate the molar mass of sodium hydroxide, which is approximately 40 g/mol. Then, multiply the molar mass by the number of moles: 40 g/mol x 0.150 mol = 6 grams of sodium hydroxide.
You were hired by a laboratory to recycle 6 moles of silver ions You were given 150 g of copper How many grams of silver can you recover Is this enough copper to recycle 6 moles of silver ions?
No you need more copper
