Question

Let atomic mass of an element be ‘A' gram. Then mass of 10 atoms of element ‘A ’ in amu is (A) (A/10) (B) (A/6.023 × 1023) (C) 10 A (D) (10A/6.023 × 1023)

R.A.M. = A amu, so 1 atom = A amu, and 10 atoms = 10 A amu

Q. Let atomic mass of an element be $‘ A^{'}$ gram. Then mass of $10$ atoms of element $‘ A ’$ in amu is

$\frac{A}{10}$

$\frac{A}{6.023 \times 1 0 ^{23}}$

$10 A$

$\frac{10 A}{6.023 \times 1 0 ^{23}}$

R.A.M. = $A$ amu, so $1$ atom = $A$ amu, and $10$ atoms = $10 A$ amu
