Answer: About 43 billion tons
Explanation:
This is gonna be quite hard to explain.
Given :
10 gram sample of propane( C₂H₈ ).
To Find :
The number of moles of propane in given sample.
Solution :
Molecular mass of propane, M = (2 × 12) + ( 1 × 8 ) gram/mol
M = 32 gram/mol
We know, number of moles is given by :
Number of moles, n = m/M
n = 10/32 mol
n = 0.3125 mol
Therefore, number of moles in given sample is 0.3125 mol.
When q is the concentration of the products / the concentration of the reactants
when the balanced equation of the reaction is:
MgCO3(s) → Mg^2+ + CO3^2-
so, Q = [Mg^2+][CO3^2-]
and we neglect the concentration of MgCO3(s) as it is in the solid phase.
when [Mg^2+] = 2.5 x 10^-3 m
[CO3^2-] = 2 x 10^-3 m
so by substitution:
Q = 2.5 x 10^-3 * 2 x 10^-3
= 0.000005 M
1μ = 10
.
Therefore, 1.5μ =
1.5 x 10.
Hope this helps, have a great day ahead!
