Question
What will be the mass of one C atom in gram _______.Select an answerA 1.99 × 10−23 B 19.9 × 10−23 C 1.99 × 1023 D 19.9 × 1023
Solution
The mass of one atom of Carbon (C) can be calculated using Avogadro's number and the molar mass of Carbon.
- Avogadro's number (N_A) is 6.022 x 10^23 atoms/mole.
- The molar mass of Carbon (M_C) is 12.01 g/mole.
The mass (m) of one atom of Carbon can be calculated using the formula:
m = M_C / N_A
Substituting the values:
m = 12.01 g/mole / 6.022 x 10^23 atoms/mole = 1.99 x 10^-23 g/atom
So, the mass of one C atom in gram is 1.99 x 10^-23 g. Therefore, the correct answer is A 1.99 × 10−23.
