Question

calculate number of moles and molecules of 11g of carbon dioxide​

Answer 1

Answer:

Mass = Mr x Moles where Mass = 11, Mr = 12 + 16 + 16 = 44. Hence, Moles = 11/44 = 0.25 moles of CO2.

Answer 2

$\boxed{\bf{\red{\bigstar Answer: }}}$

• Moles = Given mass / molecular mass
• = 11 / 44
• = 1 / 4
• Molecules = 11 × 6.022 × 10^23 / 48
