One atom of an element X weighs 6.644×10^-23 g . Calculate the no. Of gram-atoms in 40kg of it.

Question

Vikas TU · Answer

Weight of 1 atom of element = 6.644 x 10^-23g
Weight of 6.023 X 10²³ atoms of elements = 6.644 x 10^-23 x 6.023 X 10²³ = 40 g
40 g of elements = 1 g- atom
40 x 10³ g of element = 40 x 10³ /40 g = 10³ g-atom
