75 + √27
√(3*5^2) + √(3^3)
√3 * √(5^2) + √3 * √(3^2)
5√3 + 3√3 = 8√3 (ans)

Natural gas (methane) = CH4
MW = (12.0) + 4(1.01) = 16.04 g/mole
(1500 g)(1mole/16.04 g)= 93.5 moles CH4
Higher Heating Value of methane = 889 kJ/mole (from Wikipedia)
(889 kJ/mole)((93.5 moles)(1 kcal/4.184 kJ)
= 1.99 x 10^4 kcal
