9.004 g (18.0079 g/mol X 0.5 mol)
It depends upon the temperature, as when the temperature rises, water expands and therefore becomes less dense. However, at room temperature a litre of water weighs 1000g (1kg) as near as exact, and therefore a halfa litre would have a mass of half a kilogram or 500g.
p= density
V= volume
______________
p=1000 kg/m³
V=0.5 dm³=0.0005 m³
p=m/V
m=0.5kg
So the mass of 0.5l of water is 0.5kg (around 1.1 lbs)
Since the specific gravity of water is 1gm/cc, and 1 liter is 1000cc, or 1 Kg, the mass of 1 liter of water is, by definition, 1 Kg
exactly 1 kilogram.
1 L = 1,000 mL
1 kg = 1,000 g
1 mL of water = 1 g of water
nominally one half kilogram
it is 50 grams
Water bottles come in all different sizes from 330 ml to 1 L to 10L.
Molality =moles of solute/kilograms of solvent Moles of solute =2
To find the percent by mass of sugar: Mass of sugar = 35.8g Total mass of solution = 35.8g (sugar) + 125.35g (water) = 161.15g Percent by mass of sugar = (mass of sugar / total mass of solution) * 100 To find the percent by mass of water: Mass of water = 125.35g Total mass of solution = 161.15g (as calculated above) Percent by mass of water = (mass of water / total mass of solution) * 100
The mass of 100 mL of water is 100 g.
1. Find the molar mass of the hydrate (Calcium Chloride Dihydrate).Find the molar mass of water and the anhydrate (anhydrate + water = hydrate); add the molar mass values of each to find the molar mass of the hydrate.Molar Mass CaCl2: 110.98g+ Molar Mass H2O: 36.04g*Molar Mass CaCl2 * 2H2O: 147.01gFinding Molar Mass# atoms element A * atomic mass element A = Mass A# atoms element B * atomic mass element B = Mass B... etc.Add up all the mass values and you have the value for molar mass. Do this for both the anhydrate and the water molecules. Add these values together to find the molar mass of the hydrate.Molar Mass Anhydrate + Molar Mass Water Molecules* = Molar Mass Hydrate* Tip: the molar mass of water for all hydrate calculations is 18.02g x number of water molecules. This number may be useful to remember on the day of the test or while doing practice problems.*2. Calculate the percentage of water in hydrate.Divide the molar mass of water by the molar mass of the hydrate, and multiply result by 100%.36.04g147.01g x 100%Percent water in hydrate is 24.52%.
You can safely put 2ml into the 10l aquarium
they share the same volume. In the Metric system, Liters are a measurement of volume, not of weight. Therefore, 10 Liters of water would share the same volume as 10 Liters of Mercury.
10,000 mL = 10L
10kg of water contains 10l of water. So morality is 0.2mildm-3.
Water bottles come in all different sizes from 330 ml to 1 L to 10L.
10l 9l = 9l 870ml - 0.87l 9l + 0.87l = 9.87l 9.87l to the nearest whole litre is 10l (because 9.87l is closer to 10l than it is to 9l)
10L
10 Liters

1000cL equals 10L* There are 100cL per liter
10L = 1000cl
