Answer 1

Dear Student,

Gram-atom means nothing but 1 mole of substance.

◆ Answer -

0.4831 gram-atoms

● Explaination -

# Given -

M = 207 g/mol

W = 100 g

# Solution -

Number of moles of lead in given sample is calculated as -

n = W / M

n = 100 / 207

n = 0.4831 mol

Therefore, given sample of lead contains 0.4831 gram-atoms.

Thanks dear. Hope this wqs helpful...
