Correct answer is (c) 6.046 × 1023 ,51.8

Q. An element germanium crystallises in bcc type crystal structure with edge of unit cell equal to 288 pm and the density of the element equal to $7.2 g c m^{- 3}$ . The number of atoms present in $52 g$ of the crystalline element and the atomic mass of the element are respectively

$2.4053 \times 1 0^{27}, 51.8$

$3.023 \times 1 0^{23}, 48.5$

$6.046 \times 1 0^{23}, 51.8$

$6.023 \times 1 0^{23}, 60.0$

Correct answer is (c) $6.046 \times 1 0^{23}, 51.8$
