The answer depents on the density of the substance involved. If the substance is water (density = 1) then 3.45 liters would have a mass of 3.45 kilograms. 1 kilogram = 2.2406 lbs so 3.45 kg = 7.61 lbs

How many liters is 250 grams is SO3?

To convert grams to liters for a gas like SO3, you would need to know the temperature, pressure, and molar mass of the gas. Without this information, it is not possible to determine the volume in liters.


What is the mass in kilograms of 14 liters of gasoline assumi ng the density of gasoline is 0.680 grams cm3?

To convert from liters to cubic centimeters, multiply by 1000 (1 liter = 1000 cm3). Then, calculate the mass using the density formula: mass = volume x density. Therefore, the mass of 14 liters of gasoline would be 9.52 kg.


What is the molarity of 1.5 liters of an aqueous solution that contains 52 grams of lithium flouride?

The molarity of the solution can be calculated by first finding the moles of lithium fluoride using its molar mass, which is 25.94 g/mol for lithium and 19.00 g/mol for fluorine. Add these together to find the molar mass of lithium fluoride. Then, divide the mass of lithium fluoride by its molar mass to get the moles. Finally, divide the moles by the volume of the solution in liters to get the molarity.


Calculate the molarity of a hydrochloric acid solution that is 18.25 percent HCl by mass and has a density 1.2gmL?

First, calculate the mass of HCl in 100 g of the solution: 18.25% of 100 g is 18.25 g. Convert the volume to liters: 1.2 g/mL = 1.2 kg/L. Calculate molarity using the formula Molarity (M) = (moles of solute)/(volume of solution in liters), where moles of solute = mass of HCl in grams / molar mass of HCl and volume of solution = mass of solution in grams / density of solution in g/mL.


A bottle of commercial concentrated aqueous ammonia is labeled 28.89 percent NH3 by mass and density is 0.8960 grams mL. What is the molarity of the ammonia solution?

To find the molarity, first calculate the moles of NH3 in 100g of the solution using the mass percent. Then convert the volume of the solution (1 mL) to liters. Finally, divide moles by liters to obtain the molarity.
