Answer
$102^{\circ}F$
Work Step by Step
We know: T = t+ 273.15
where T is the temperature in Kelvin and t is the temperature in Celsius.
Then: t=$ (312.0- 273.15)^{\circ}C= 38.85^{\circ}C$
To convert the temperature to Fahrenheit:
We use the relation: F= $\frac{9}{5}C+32$
Which gives: F= $\frac{9}{5}×38.85+32$ =101.93°F$\approx$102°F
