Honestly, you can look at the notes you took and even look down some things in google to help u solve ur answer
Molar mass:
O2 = 31.99 g/mol
C8H18 = 144.22 g/mol
<span>2 C8H18(g) + 25 O2(g) = 16 CO2(g) + 18 H2O(g)
2 x 144.22 g --------------- 25 x 31.99 g
10.0 g ----------------------?? ( mass of O2)
10.0 x 25 x 31.99 / 2 x 144.22 =
7997.5 / 288.44 => 27.72 g of O2
hope this helps!

Answer:
163.44 g
Explanation:
We know that one ton is equal to 2000 lbs and one lb is equal to 454 grams.
Solution:
1.80 × 10∧-4 ton× 2000 lb/ton× 454 g/lb
1.80 × 10∧-4 ton× 2× 10³lb/ton× 454 g/lb
1634.4 g/ 10 = 163.44 g
We are given the rate law, so we can substitute the given values for the rate constant and the concentrations of the reactants to solve for the rate of reaction. Since rate = k [NH4+][NO2-]:
rate = (2.7 x 10^-4 / M-s)(0.050 M)(0.25 M) = 3.375 x 10^-6 M/s
