What is the molarity of a solution of 3 moles of FeBr3 in 5 L water?
0.6 mol/dm3
How do you calculate the mass of 5.68 L NO at STP?
At STP 1 mole of every gas has the volume of 22.4 dm3. (1 dm3 = 1 L)According to previous law, 1 mol - 22.4 dm3 x - 5.68 dm3-------------------------- x = 0.2536 mol1 mol of NO weights 30 g (Ar for N is 14, and Ar for O is 16. Mr(NO) = Ar(N) + Ar(O)), so1 mol - 30 g0.2536 mol - x------------------------------x = 7.6080 gSo the mass of 5.68 L of NO at STP is 7.6080 grams.
How many moles of HCl are dissolved in 2.0 L of 0.25 M HCl solution?
0.5 Moles If you have a 0.25 M solution, you have 0.25 mol/dm3, or 0.25 moles in 1 L (0.25 mol/L) If you have 2 L of solution, you have 2 L x 0.25 mol/L = 0.5 mol The L's cancel out, and you're left with moles.
When C3h4 combustion at STP 5.6l of c3h4 are consumed how many moles of c3h4 react?
5.6 dm3 is divided by 22.4 dm3 to give number of moles: =5.6dm3/22.4moles per dm3 =0.25 moles So 0.25 moles of C3H4 react.
What is liquid usually measured in?
milliliters, mL; liters, L; pints, cups, gallons SI unit for volume is cubic meter/metre so cm3 = mL; dm3 = L
What unit expresses volume?
the unit that that expresses volume is hertz
How many dm3 in 300 cm3?
300 cm3 equals 0.3 dm3
If an aquarium is 120 dm3 how many liters does it contain?
120 dm3 = 120 liters
What is the abbreviation of 'liter'?
L is and abbreviation for litre and is a unit of volume used for liquids equivalent to a dm3 or 1000 cc.The abbreviation is ltr or l

How much does 1 liter of LPG equal in cubic meters?
1000 L = 1 m3 1L = 1 dm3 1 L = 1000 cm3
What is 400 cm3 in dm3?
400 cm3 to dm3
What has its own density?
Each material has its own density!Examples: Solid - water - noble gasCopper has a density of 8950 kg/m3 = 8.95 kg/dm3 = 8.95 g/cm3.Water has a density of 1000 kg/m3 = 1000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL.Helium has a density of 0.1785 kg/m3 = 0.1785 g/L = 0.0001785 kg/dm3 = 0.0001785 kg/L =0.0001785 g/cm3 = 0.0001785 g/mL.
When is it helpful to use density?
If you do not know which material you have, knowing the density can help you identify it. Examples: Solid - water - noble gasCopper has a density of 8950 kg/m3 = 8.95 kg/dm3 = 8.95 g/cm3.Water has a density of 1000 kg/m3 = 1000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL.Helium has a density of 0.1785 kg/m3 = 0.1785 g/L = 0.0001785 kg/dm3 = 0.0001785 kg/L =0.0001785 g/cm3 = 0.0001785 g/mL.
Why do you use density?
Because every material has its own density. Examples:Solid - water - noble gasCopper has a density of 8950 kg/m3 = 8.95 kg/dm3 = 8.95 g/cm3.Water has a density of 1000 kg/m3 = 1000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL.Helium has a density of 0.1785 kg/m3 = 0.1785 g/L = 0.0001785 kg/dm3 = 0.0001785 kg/L =0.0001785 g/cm3 = 0.0001785 g/mL.
What is density an example of?
