Gas Constant (R - Any gas) = Universal Gas constant / Molecular mass of that particular gas.
Hence, Universal Gas Constant (Runiv) = Rgas x Mgas.
Hence, Universal Gas Constant (Runiv) = Rgas x Mgas.

R=Ru/M.
THEN,
Ru=R*M.
THEN,
Ru=R*M.

M = Ru/R.
Then, Ru = M*R.
Then, Ru = M*R.

M means molecular weight. And m means molecular mass.
Formula is M*R. So statement should incorrect.
Formula is M*R. So statement should incorrect.

R1 = R/M from this we get R = R1*M, where R1 = Gas constant.

PV = nmRT.
N = Number of moles.
R = Characteristics gas constant.
M = Mass of the gas.
T = Temperature.
Now,
M x n = Molecular mass = M.
M x R = Ru universal gas constant.
Now the equation is written as:
PV = RuT.
N = Number of moles.
R = Characteristics gas constant.
M = Mass of the gas.
T = Temperature.
Now,
M x n = Molecular mass = M.
M x R = Ru universal gas constant.
Now the equation is written as:
PV = RuT.

pV = mRT ideal gas equation.
m = mass, R = characteristics gas constant, T = temperature, p = pressure and V = volume.
m=n*M where M=molecular mass(mass of one molecules) and n = no of moles.
So pV = nMRT.
pv=n(R)T. (R)=UNIVERSAL GAS CONSTANT.
This proves (R) = MR.

pv = nRt.
R = PV/t (n=1);
R = P*M/density*T.
R = (P/T)*M.
R = PV/t (n=1);
R = P*M/density*T.
R = (P/T)*M.
