Question

Calculate the mass of 6.022×10²⁴atoms of carbon.

Answer 1

atomic mass of carbon = 12 amu
molar mass of carbon = mass of 6.022×10²³atoms of carbon
= 12g

Mass of 6.022 × ${10}^{23}$ atoms of Carbon = 12 g

Mass of 6.022 × ${10}^{24}$ atoms of Carbon =?

=$\frac{6.022\times {10}^{24}}{6.022\times {10}^{23}}\times 12=120g$

Therefore, the mass of 6.022×${10}^{24}$ atoms of carbon=120g
