Estimate the mass of the following substance contained in the size $D$ cylinder at $20C$ and $25$ bar. The values of $R$ are

given in the following table:

Values of the Universal Gas Constant

$R=8\mathrm{.}314J*mo{l}^{-1}*K^{-1}=8\mathrm{.}314m^3*Pa*mo{l}^{-1}*K^{-1}$

$=83\mathrm{.}14c{m}^3\frac{*}{b}ar*mo{l}^{-1}*K^{-1}=8314c{m}^3*kPa*mo{l}^{-1}*K^{-1}$

$=82\mathrm{.}06c{m}^3*(atm)*mo{l}^{-1}{K}^{-1}=62,356c{m}^3*(torr)*mo{l}^{-1}*K^{-1}$

$=1\mathrm{.}987(cal)*mo{l}^{-1}*K^{-1}=1\mathrm{.}986(Btu)(lbmole{)}^{-1}(R{)}^{-1}$

$=0\mathrm{.}7302(ft{)}^3(atm)(lbmol{)}^{-1}(R{)}^{-1}=10\mathrm{.}73(ft{)}^3(a)(lbmol{)}^{-1}(R{)}^{-1}$

$=1545(ft)(l{b}_f)(lbmol{)}^{-1}(R{)}^{-1}$

A size D compressed gas cylinder has an internal volume of $2\mathrm{.}40$ liters.

Consider arsine, $As{H}_3,$ for which $T_C=373K,P_C=65\mathrm{.}5$ bar, and $=0\mathrm{.}011.$

The mass of $As{H}_3$ is
