Question

Calculate the number of Cu atoms in 0.635g of Cu.

Answer 1

Answer:

The atomic mass of Copper ( Cu ) is 63.5 u . There fore , the molar mass of Copper is 63.5 g . So , 63.5 g of Cu will contain 6.022 * 10^23 . So , 0.635 g of Cu will contain 6.022 * 10^23 / 100 = 6.022 * 10^21 .

Answer 2

Answer:

Cu will contain 6.022 * 10^23 / 100 = 6.022 * 10^21

Explanation:Cu will contain 6.022 * 10^23 / 100 = 6.022 * 10^21

The atomic mass of Copper ( Cu ) is 63.5 u . There fore , the molar mass of Copper is 63.5 g . So , 63.5 g of Cu will contain 6.022 * 10^23 . So , 0.635 g of Cu will contain 6.022 * 10^23 / 100 = 6.022 * 10^21
