Approx. 1g/ml density so 2kg
A liter of water weighs 1 kilogram or 1000 grams. Half a liter (.5 l) will weigh half that, or 500 grams.
There is one gram per ML of water, and 1000 ML in a liter. There are 2,000 grams or two kilograms in two liters of water.
To calculate the mass of water, you can multiply the density of water (1 g/cm3 or 1000 kg/m3) by the volume of water. The formula is: mass = density x volume. For example, if you have 1 liter of water, the mass would be 1000 grams.
The conversion from grams to liters depends on the density of the substance. To convert 40 grams to liters, you would need to know the density of the specific material. The formula for this conversion is: volume (liters) = mass (grams) / density (grams per liter).
This question cannot be answered sensibly. A litre is a measure of volume, with dimensions [L3]. A gram is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information. As a simple mental exercise consider a litre of air and a litre of water. They will have very different masses.
Kilogram is mass. Liter is volume. The only way you can relate the two is if you have a substance of known density. For example, water has a density of 1 kg per liter.
Just add the two masses: 40 + 120 = 160 grams.
To find the concentration of a solution in grams per liter, you need to divide the mass of the solute (in this case, 80 grams of NaCl) by the volume of the solution (2 liters). Therefore, the concentration of the solution would be 80 grams divided by 2 liters, which equals 40 grams per liter.
You multiply by the density. Density is usually given grams per milliliter or kilograms per liter or grams per cubic centimeter, which are all interchangeable. Multiply by the density and then multiply by 1000 if given in one of the above units.
The mass of a single quarter is approximately 5.67 grams. Therefore, the mass of two quarters would be about 11.34 grams.
A gram is a unit of mass. A litre is a unit of capacity. Without a measure of density to compare, the two units are incompatible.
1 liter is 1000 milliliters and water is 1 gram per milliliter, so one liter water = 1000 grams 1000 grams H2O (1 mole H2O/18.016 grams) = 55.5 moles of water -----------------------------
