To calculate the moles of C3H4 consumed, we can use the ideal gas law equation PV = nRT at STP conditions (standard temperature and pressure). Since the volume (V) is 5.6 L, and at STP conditions 1 mole of gas occupies 22.4 L, we can calculate the number of moles of C3H4 consumed as (5.6 L / 22.4 L/mol) = 0.25 moles.
98 g per dm3 would be 1 molar - so 49 g would be 0.5 molar , so 4.9 g is 0.05 mol per dm3 or 0.05 mol.dm-3
In pure water, the concentration of H3O plus (hydronium ion, H3O+) is 1.0 x 10^-7 mol/L and the concentration of OH- (hydroxide ion) is also 1.0 x 10^-7 mol/L. This represents a balanced state of neutrality.
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.
Volume, represented by "dm3," is a physical property, indicating the amount of space occupied by a substance. In this case, 15 dm3 refers to a specific volume measurement and is a physical quantity.
the unit that that expresses volume is hertz
300 cm3 equals 0.3 dm3
120 dm3 = 120 liters
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
To calculate the moles of C3H4 consumed, we can use the ideal gas law equation PV = nRT at STP conditions (standard temperature and pressure).

The molar volume of any ideal gas at standard temperature and pressure (STP) is 22.4 L/mol. Converting 39.6 dm3 to liters gives 39.6 L. To find the mass of argon gas, we calculate the number of moles using the ideal gas equation (PV = nRT) and then multiply by the molar mass of argon.
400 cm3 to dm3
1000 L = 1 m3 1L = 1 dm3 1 L = 1000 cm3
1 dm3 = 1000 cm3 :)
1 dm³ (cubic decimeter) is equal to 1 liter (L). This is because the liter is defined as the volume of a cube that measures 10 centimeters on each side, which is equivalent to a cubic decimeter. Therefore, 1 dm³ = 1 L.
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.
