Question

how many gram of 0.5 mol of copper atoms​

Answer 1

One mole of copper, 6.022×1023 individual copper atoms have a mass of 63.55⋅g.

Answer 2

31.75 grams of copper is used to get 0.5 moles of copper atoms.​

• The number of moles of a compound can be calculated by dividing the given mass of the compound by the molar mass of the compound.
• The number of moles of copper is given which is equal to 0.5 moles.
• As we know, that the molar mass of copper is equal to 63.5 grams.
• The formula used to determine the given mass of the copper is as follow:

        $Number of moles = \frac{Given mass}{Molar mass}$

        = $0.5 = \frac{Given mass}{63.5}$

        = Given mass = 0.5 × 63.5

         = 31.75 grams of copper

Hence, 31.75 grams of copper is used to get 0.5 moles of copper atoms.
