Question

How many grams of silicon are present in 35 gram atoms of silicon(Given at. wt. of Si =28)

Answer 1

Gram atoms = number of moles of atoms.=> number of moles of silver atom = 35 .then,and we know that atomic mass of a Silver atom is : 28 u .=> mass of 1 mol of silver atoms is = 28g Then,Mass of 35 moles of silver atoms =35×28 grams= 980 grams _________________hope it helps !

Answer 2

Answer:

980 grams.

Explanation:

1 gram atom of silicon weighs 28 g.

35 gram atoms of the same will weigh  28 x 35 = 980 g.
