A one peso coin weighs 20 grams and contains 75% copper by mass. To find the amount of copper, multiply the total mass by the percentage of copper: 20 grams × 0.75 = 15 grams. Therefore, there are 15 grams of copper in a one peso coin.
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.
To find the mass of copper containing the same number of atoms as in 3.2 grams of sulfur, we first determine the number of moles of sulfur. Sulfur has a molar mass of approximately 32 g/mol, so 3.2 grams corresponds to 0.1 moles of sulfur. Since copper (Cu) has a molar mass of about 63.5 g/mol, the mass of copper that has the same number of moles (0.1 moles) is calculated as 0.1 moles × 63.5 g/mol = 6.35 grams. Therefore, the mass of copper is 6.35 grams.
The mass of 1.1g of copper is 1.1 grams.

The lowest whole number mass ratio of copper that combines with a given mass of chlorine is 1:1, meaning each mole of copper combines with one mole of chlorine. This corresponds to the compound copper (I) chloride, where the mass ratio would be 63.5 grams of copper to 35.5 grams of chlorine.
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.

Since copper (Cu) has a molar mass of about 63.5 g/mol, the mass of copper that has the same number of moles (0.1 moles) is calculated as 0.1 moles × 63.5 g/mol = 6.35 grams. Therefore, the mass of copper is 6.35 grams.
The mass of 1.1g of copper is 1.1 grams.

The molar mass of copper is 63.55 grams per mole.
To calculate the mass of copper in grams, you first need to find the molar mass of copper, which is approximately 63.55 g/mol. Then, multiply the number of moles (0.0420 moles) by the molar mass to get the mass in grams. Mass = moles x molar mass Mass = 0.0420 moles x 63.55 g/mol = 2.67 grams of copper.
The density of copper is 8.94 grams per cm3. The mass will depend on the volume of the "lump" of copper.
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.
The periodic table states that the molar mass of copper is 63.546 grams per mole. That means that if you have one mole of copper, it will weigh 63.546 grams. One mole is 6.022x1023 (Avogadro's number) atoms. To find the mass of one copper atom in grams, you simply divide copper's molar mass by the number of atoms in one mole. 63.546 / 6.022x1023 = 1.055x10-22 One atom of copper weighs 1.055x10-22 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.

To find the mass of a piece of copper, you can use the formula: mass = volume × density. Given that the volume is 5.00 cubic centimeters and the density of copper is 8.96 grams per cubic centimeter, the mass would be 5.00 cm³ × 8.96 g/cm³ = 44.80 grams. Thus, the mass of the copper piece is 44.80 grams.
