A mole of any chemical compound contains the same number of molecules - about 6.022 × 10²³ molecules.
So, 1 mole of H₂O₂, 1 mole of C₂H₂ and 1 mole of CO contain the same number of molecules.
Answer:
we use: V = pi*(r^2)*h
V = 3.14*(12.0cm^2)*44.0 cm
V = 19895.04 cm^3
Therefore, mass = (8.90g/cm^3) * (19895.04 cm^3) = 177065.856 g
Explanation:
I can help you but what is the question here?
Answer:
I think it's
(A) A telescope is an instrument that magnifies tiny objects to make them appear bigger
The number of O atoms that ate in 1.25 mol of SO2 is 2.5 moles
<em><u>calculation</u></em>
moles of O= total number O atoms in SO2 x 1.25 moles
The number of O atoms in SO2 = 1 x2 = 2 atoms
moles is therefore= 2 x 1.25 moles = 2.5 moles
