Question

One dozen apple = 12 apple One pair pen = 2 pen So one mole of wheat grains is equal to 1) 6.022 * 10 wheat grains 3) 1.66056 * 10 wheat grains 2) 1.66056 x 1023 wheat grains 4) cannot predicted​

Answer 1

Answer:

I mole wheat grain is 6.022*10^23 grains.

Answer 2

Answer:

The correct answer is option 1)6.022 × 10²³ wheat grains.

Explanation:

We know that one mole of a substance contains one unit of Avogadro's number.

• Avogadro's number is a constant that is equal to 6.022 × 10²³.
• Therefore, as one dozen contains 12 units and pair comprises of two units.
• One mole a substance contains 6.022 × 10²³ units.
• Thus, one mole of wheat grains is equal to 6.022 × 10²³ wheat grains.

Hence, the correct answer is option 1)6.022 × 10²³ wheat grains.
