What is the unit of specific weight of argon?
Argon – Density and Specific Weight Density, 蟻, has units typically [kg/m3] or [lb/ft3], and is defined by the ratio of the mass to the volume of a substance: 蟻 = m/V where m = mass, units typically [kg] or [lb]
What is the mass of 540l of argon gas in grams?
One litre of any gas at STP has a volume of 22.4 L So # (540L)/ (22.4L) = 25 moles of argon 25 moles Ar x 39.948 g/mol = 998.7 g Since you started with a measurement containing only two significant digits, your answer can only contain two significant digits, so it rounds to 1.0×10^3 g (or 1.0 kg)
What is the weight of 25 moles of argon in liters?
One mole of Argon weighs 39.948g. One litre of any gas at STP has a volume of 22.4 L. So #(540L)/(22.4L) = 25 moles of argon.
What is the kg/m value of STP?
2) STP – Standard Temperature and Pressure – is defined as 0 oC (273.15 K, 32 oF) and 1 atm (101.325 kN/m 2, 101.325 kPa, 14.7 psia, 0 psig, 30 in Hg, 760 torr) 1 lb m/ft 3 = 16.018 kg/m 3 1 kg/m 3 = 0.0624 lb m/ft 3
