Answer:
The answer to your question is: Volume = 1.074 x 10⁻⁶ m³
Explanation:
Data
Salt crystal measures 5.44 x 10⁻² m ; 2.5 x 10⁻³ m; 7.9 x 10⁻³ m
From the information I suppose it is a cube, then,
Volume of a cube = length x width x height
Volume = 5.44 x 10⁻² m x 2.5 x 10⁻³ m x 7.9 x 10⁻³ m
Volume = 0.000001074 m³
Volume = 1.074 x 10⁻⁶ m³
Molar mass O2 = 31.99 g/mol
Molar mass CO2 = 44.01 g/mol
Moles ratio:
<span>C3H8 + 5 O2 = 3 CO2 + 4 H2O
</span>
5 x 44.01 g O2 ---------------- 3 x 44.01 g CO2
( mass of O2) ------------------ 37.15 g CO2
mass of O2 = 37.15 x 5 x 44.01/ 3 x 44.01
mass of O2 = 8174.8575 / 132.03
mass of O2 = 61.916 g
Therefore:
1 mole O2 ----------------- 31.99 g
moles O2 -------------------- 61.916
moles O2 = 61.916 x 1 / 31.99
moles = 61.916 / 31.99 => 1.935 moles of O2
