A cooking gas cylinder is assumed to contain 6.7 kg of fuel gas (molar mass 58 g/mol). The heat of combustion of fuel gas is 2465 kJ/mol. A family needs 8 x 103 kJ of energy per day of cooking. Then how long would cylinder will last (approx.)? (Assume 29% of gas goes waste due to incomplete combustion).

Arecipe calls for 1.2 cups of oil. how many liters of oil is this?

How many moles of oxygen react with 12 moles of aluminum

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
