# Estimate the mass (in kg) of 1 gallon of water

May 04, 2019 · The density of water is the weight of the water per its unit volume, which depends on the temperature of the water. The usual value used in calculations is 1 gram per milliliter (1 g/ml) or 1 gram per cubic centimeter (1 g/cm 3). While you can round the density to 1 gram per milliliter, there are more precise values for you to use.

1. Record the mass of a 50 mL beaker. 2. Add 25 mL of deionized water from a DI water bottle to the beaker and record the mass. 3. Empty the water in the sink, dry the beaker, and record the mass of the dry beaker.

If the air mass is measured in grams, then the calculated amount of fuel will also be in grams. Using an average density of gasoline of 6.17 pounds per gallon and knowing that there are 454 grams per pound, then dividing the total fuel mass in grams by (454 * 6.17) yields the total number of gallons of fuel burned for a given amount of air (as ...

Therefore, for a conventional process, an economy of approximately 1.35 kg BOD removed per kWh is common. Example 4-12 : Assuming an oxygen transfer efficiency of 6 %, calculate the air required per capita for an activated sludge plant removing 0.04 kg BOD / capita . day, assuming 1.30 kg O 2 / kg BOD removed.

(water density = 1.0 × 103 kg/m3) a. 0.060 m b. 0.015 m c. 0.030 m d. 0.075 m 20. The bottom of a flat-bottomed aluminum boat has area = 4.0 m2 and mass = 60 kg. If two fishermen and their fishing gear with total mass of 300 kg are placed in the boat, how much lower will the boat ride in the water? (H2O density = 1.0 × 10 3 kg/m3) a. 0.15 m b ...

3. Calculate the change of enthalpy that occurs when 5 kg of water at 70°C in a closed vessel of 0.50 m3 in volume are heated to 453.1 K and 1000 kPa. Also determine the final quality of the steam in the vessel. Ans. DH = 7520 kJ ; x = 0.51 4. Determine Q, W, U and H for the isothermal expansion of 1.31 mol of an ideal gas against

Weight: Gas: Liquid: pounds (lb) kilograms (kg) cubic feet (scf) cu meters (Nm 3): gallons (gal) liters (l) 1 pound: 1.0: 0.4536: 12.076: 0.3174: 0.105: 0.3977: 1 ...

1.101 g/mL. Step 1. Make an assumption. Assume you have 1 kg of solvent (water). This is a very important step and the amount of solution is not given but you need to have a specific quantity to do the calculations and one kilogram is the best assumption. Step 2. Find the total mass of HF (solute). 21.4 m means 21.4 moles /kg solvent (water).

Calculate the mass (in kg) of water produced from the combustion of 1.0 gallon (3.8 L) of gasoline (C8H18). The density of gasoline is 0.79 g/mL. +0 (1) Answers. Obdulia548 . May 27, 2017, 10:19:07 PM. 1) first, we need to write down the reaction equation for this combustion.How much energy is required to convert 1 kg of ice at 0o C to 1 kg of water at 0oC ? How much energy is required to convert 1 kg of water at 100o C to 1 kg of steam at 100oC ? Example : Calculate the amount of heat energy required to change 20 g of ice at -20oC into steam at 100oC. Given that . s.h.c. ( water ) = 4,200 J kg-1 K-1. s.h.c. ( ice ... Calculate the mass (in kg) of water produced from the combustion of 1.0 gallon (3.8 L) of gasoline (C8H18). The density of gasoline is 0.79 g/mL. +0 (1) Answers. Obdulia548 . May 27, 2017, 10:19:07 PM. 1) first, we need to write down the reaction equation for this combustion.The 5-kg mass is heavier than the dog, so take it off the pan and place a 1-kg mass on the pan. Add 1-kg masses to the left pan until it goes down. Then take one of the 1-kg masses off the pan so that the masses are above the dog. Jun 25, 2016 · A piece of ice of mass 40 g is dropped into 200 g of water at 50°C. Calculate the final temperature of water after all the ice has melted. Specific heat capacity of water = 4200 J/kg o C , Specific latent heat of fusion of ice = 336 x 10 3 J/kg. Fuel oil: 29.3 gallons per home × 1/42 barrels/gallon × 429.61 kg CO 2 /barrel × 1/1,000 kg/metric ton = 0.30 metric tons CO 2 /home Total CO 2 emissions for energy use per home: 5.906 metric tons CO 2 for electricity + 2.21 metric tons CO 2 for natural gas + 0.25 metric tons CO 2 for liquid petroleum gas + 0.30 metric tons CO 2 for fuel oil ...
