Particles in a liquid move freely and liquids have a definite volume and indefinite shape since it occupies the shape of the container in which the liquid is in.
Molar mass helium gas :
He = 4.0 g/mol
number of moles: 3.75 / 4.0 => 0.9375 moles
1 mole ------ 22.4 ( at STP)
0.9375 ------ ?
volume = 0.9375 x 22.4 / 1
Volume = 21 / 1
Volume = 21 L
hope this helps!
Answer: 0.025 moles of nitrogen gas are there in the sample.
Explanation:
According to ideal gas equation:
P = pressure of gas = 1.03 atm
V = Volume of gas = 568 ml = 0.568 L (1L=1000ml)
n = number of moles = ?
R = gas constant =
T =temperature =
0.025 moles of nitrogen gas are there in the sample.
