4/14/-1 Resources Hint Question 15 of 16 > Suppose a boil water notice is sent out advising all residents in the area to boil their water before drinking it or using it for cooking. You need to boil 18.5 L of water using your natural gas (primarily methane) stove. What volume of natural gas is needed to boil the water if only 19.7% of the heat generated goes towards heating the water. Assume the density of methane is 0.668 g/L,...
