How many grams of copper in eight grams of gold?
There is no copper in gold unless it has been intentionally added in an alloy. If you are referring to an alloy such as rose gold, the amount of copper would depend on the specific composition of the alloy.
What is 40 grams of copper chloride dissolved in 120 grams of water what is the mass of the solution?
Just add the two masses: 40 + 120 = 160 grams.
Is the mass of 0.50 mole of copper is 32 grams?
No, the molar mass of copper is approximately 63.55 grams per mole. Therefore, the mass of 0.50 moles of copper would be 0.50 moles x 63.55 g/mol = 31.77 grams.
How much copper sulfate would be needed to make a saturated solution of copper sulfate with 400g of water at 20 degree celsius?
To prepare a saturated solution of copper sulfate at 20 degrees Celsius, you would need to dissolve approximately 203 grams of copper sulfate in 400 grams of water. This is based on the solubility of copper sulfate in water at that temperature.
What is the mass of 19 atoms of copper in grams?
To calculate the mass of 19 atoms of copper in grams, you need to determine the molar mass of copper. The molar mass of copper is approximately 63.55 grams per mole. Then, you can use Avogadro's number (6.022 x 10^23 atoms per mole) to convert atoms to grams. So, the mass of 19 atoms of copper would be 19*(63.55/6.022e23) grams.
If you have 6.50 molar of chromium which is a molar mass of 52 grams what is the amount in grams of this amount of chromium?
To calculate the amount in grams of chromium in a 6.50 M solution, you would multiply the molarity (6.50 mol/L) by the molar mass of chromium (52 g/mol). This gives you 338g of chromium in 6.50 L of the solution.
How many grams of copper are in a one peso coin containing 75 copper by mass?
A one peso coin weighing 10 grams and containing 75% copper by mass would have 7.5 grams of copper. This is calculated by multiplying the total mass of the coin (10 grams) by the percentage of copper (0.75): 10 grams × 0.75 = 7.5 grams of copper.

How much will 35 grams of copper cost if 14 grams of copper cost 80 dollars?
35 grams of copper will cost $200. Since 14 grams cost $80, we can calculate the cost per gram by dividing $80 by 14 to get the cost per gram. Then, we can multiply the cost per gram by 35 to find the total cost for 35 grams.
How many new pennies make a pound of copper?
One modern cent weighs 2.5 grams and contains 2.5% copper, which is 0.0625 grams or about 0.000138 lbs of copper per penny. To get one full pound of copper, it would take 7,246 pennies.

If your body was reduced to chemicals how much would you cost?
If you weighed 68000 grams, 44200 grams would be oxygen, 12240 grams would be carbon, 6800 grams would be hydrogen, 2040 grams would be nitrogen, 1020 grams would be carbon, 816 grams would be phosphorous, you would have 136 grams each of chlorine, sulfur, and potassium, 68 grams would be sodium, 34 grams would be magnesium, and you would have about 136 grams of iron, cobalt, copper, zinc, and iodine combined, and 13.6 grams of selenium and fluorine combined. You do the rest.
Chromium forms two bromides one that is 17.82percent chromium by mass and another that is 24.55 percent chromium. In the first sample the mass of chromium per 1 gram of bromide?
Chromium form three (not only two) bromides: * CrBr2, containing 24,759 85 % chromium * CrBr3, containing 17,991 45 % chromium * CrBr4, containing 14,129 09 % chromium 1 gram of CrBr3 contain 179,91 45 mg chromium.
How many copper pennies does it take to make a pound?
In 1 pound of pre-1982 copper pennies, there are approx 448 grams of weight. Knowing that a copper pre-82 penny weighs 3.11 grams, simply divide the approx 448 grams in 1 pound by the individual penny weight of 3.11grams. The answer to"how many copper pennies does it take to make a pound" is this.It would take 144.05144 copper pennies to weight 1 pound........give or take a couple.One copper cent weighs 3.11 grams, and one pound is 453.59 grams. Do the math, and it comes out to 146 copper cents per pound.
