You have decided to go on a road trip with your friends to Joshua Tree National Park (the desert!) in September. There is a total of 5 of you going and you are planning on staying for 3 full days. You are unsure if your car can handle the weight of the water you want to bring. After accounting for the mass of every person in the car, you can hold up to 125 pounds of water. You identity you will need 1.85 gallons of water for each person for each day you are staying. What mass, in pounds, of water would this require you to bring? Use the density of water of 1.00 g/ml.

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
