The atomic mass of an element is 50
(i) Calculate the number of atoms in its 10 gm
(ii) What mass of the element contains `3.011xx10^(20)` atoms

Explanation

To solve the problem step by step, we will break it down into two parts as given in the question.

### Part (i): Calculate the number of atoms in 10 grams of the element.

**Step 1:** Identify the atomic mass and Avogadro's number.
- The atomic mass of the element is given as 50 g/mol.
- Avogadro's number (the number of atoms in one mole) is \(6.022 \times 10^{23}\) atoms/mol.
