On a 7 day wilderness expedition you'll need to heat 5.0 kg of water to the boiling point each day. The air temperature will average 25 °C. You have available canisters of compressed butane (CH₁0) fuel, which you'll burn to heat the water. Each canister has 75. g of butane in it. What is the minimum number of fuel canisters you must bring? 10, The standard heat of formation of butane at 25 °C is -125.7 kJ/mol. You'll probably find other helpful data in the ALEKS Data resource. Nathan ✔

To determine the density of liquid samples. 2. To form a layer of four given liquid (one on top of the other) according to the density, from bottom up. Apparatus : Platform balance, 1 - 25 mL test tube, 1 - 10 mL graduated cylinder, 2 - mL colored water, 2 – mL coconut oil, 4 pcs. Vials. 2 - mL colored alcohol, 2 - mL kerosene Materials : Theory: Density is best described as the compactness of a substance. The more compact is the substance the in a small space the heavier is the substance. For a less dense substance, the mass is spread out over a large volume of space. It is a measurement of how heavy of light is the substance Its mathematical expression is density is the ratio of an object's mass to its volume. The density of a material…
