1 mole CO₂----------- 6.02x10²³ molecules
4 moles CO₂ ---------- ??
4 x ( 6.02x10²³) / 1 =
= 2.41 x 10²⁴ / 1 => 2.41 x 10²⁴ molecules of CO₂
Answer C
Given a mole each for iron and magnesium, the number of atoms of each element is equal. Iron has a greater mass due to its greater molecular weight. The correct statement among the choices is D.
Find the molar mass of CaCO3 then subtract the molar mass what it originally weighed and the loss of mass. Hopefully this works!
