THIS USER ASKED π
The molecular mass of octane is 114.22 g/mol. what is the mass of 22.05 mol of octane? 5.180 g 22.05 g 114.22 g 2,518 g
THIS IS THE BEST ANSWER π
Correct Answer
Fourth Choice, 2518 g
Solution:
The formula of the number of moles (n) in terms of the mass of the compound (m) and the recommended mass of the compound (M) can be expressed as follows:
We have the number of Octane moles.
So,
n = 22.05 moles
We have an octane molar mass.
So,
M = 114.22 g / mol
Using these values ββin the formula above we can calculate the mass of Octane (m).
Thus, the mass is 22.05 moles Octane 2518 g.
