t = 1900 seconds is essentially the "x-axis"
so
finding "y-axis" will give us ln([SO2Cl2])
so...
the equation
y = -0.000290*t - 2.30
substitute t= 1900
y = -0.000290*1900 - 2.30 = - 2.851
note that
y = ln(C)
ln(C) = -2.851
C = exp(-2.851) = 0.05778 of SO2Cl2
the concentration is epxected to be about 0.05778 M of SO2Cl2
[SO2Cl2] = 0.05778 M
