Can you Tap a Sac Land for Mana to Trigger an ability then Sacrifice it? | tcgmode

I have the World Shaper precon and I was wondering about this. When I station Hearthhull for 2 it lets me tap a land, then tap Hearthhull, then I sacrifice a land to draw two. Can I tap say Rocky Tar Pit for the mana needed to tap Hearthhull, then sac that land?
