Calculation of gas molar mass by density method under standard condition M = V ρ = 22.4l/molx ρ standard
M gas mass, V gas volume, VM gas molar volume, ρ gas density
m = ρ*V
V = n*Vm
Substitute M = ρ * n * VM
Divide n to the left
m/n = ρ*Vm
That is, M = ρ * VM
Under standard condition, M = ρ standard * 22.4l/mol

First, find a straight hard rod, hang it at o point with a thin line, and the hard rod is balanced in the horizontal position. Then hang the metal block B with known density of ρ at C on the left end of the hard rod, and find a weight a at the right end of the hard rod, and adjust the weight a At this time, the position of the weight hanging on the hard rod is e, as shown in the figure. The following is part of the experimental steps for Xiaodong to measure ρ oil. Please complete the experimental steps according to Xiaodong's experimental ideas (1) Measure the length l0 of OE with a scale; (2) immerse the metal block B in the oil to be measured, and move the weight a from e to D, and the hard rod will be balanced in the horizontal position again; (3)___ (4) the formula for calculating ρ oil by using the physical quantity measured above and the known quantity in the question is as follows:___ .
