Claudio Ranieri's Roma move to within a point of fourth-placed Inter Milan, who host Chievo on Monday. "Even if not everything depends on us, we have to get to the end with a clear conscience".
AC Milan also won 1-0 against Fiorentina, and are one point behind Inter in fifth, with Roma equal on points with Milan, with two games left to play.
Juventus, who wrapped up the title with five games to spare, wore their new strip despite many fans objecting to the decision on social media.
Juventus had started the game brightly as Ronaldo fired wide, Juan Cuadrado had a shot saved by Antonio Mirante and Leonardo Spinazzola saw a shot blocked, all inside the first seven minutes of the match. Cristiano Ronaldo mocked Alessandro Florenzi's height during AS Roma v Juventus.
Juventus thought they had the lead just after the hour when Dybala played in Ronaldo to finish, but after VAR took a look the goal was ruled out for offside.
His side then bagged a second goal thanks to a late strike from Edin Dzeko.
"We knew very well how important it was to win today", said Belotti.
Belotti nearly scored after the break but Sassuolo goalkeeper Andrea Consigli denied his overhead kick.
Sassuolo are sitting in tenth position.
