Question

Number of particles in 8g of CO2

Answer 1

$\textbf{\huge{\underline{ Hello Mate! }}}$

Atomic mass of CO2 can be taken out as follows,

= ( 12 + 16 × 2 ) g/mol

= 44 g/mol

No. of moles = W g / W g/mol

= 8 g / 44 g/mol

= 0.182 moles

Since, 1 mole = 6.022 × $10^{23}$ atomes

0.182 mole = 0.182 × 6.022 × $10^{23}$

= 1.1 × $10^{23}$ atoms.

Answer 2

Answer:

Atomic mass of CO2 can be taken out as follows,

= ( 12 + 16 × 2 ) g/mol

= 44 g/mol

No. of moles = W g / W g/mol

= 8 g / 44 g/mol

= 0.182 moles

Since, 1 mole = 6.022 ×  atomes

0.182 mole = 0.182 × 6.022 ×

= 1.1 ×  atoms. THANK U
