The thing that has helped me and even is helping me as I am writing this is Grammarly! I LOVE IT!
This is a complex sentence it includes a subordinate clause (one that CANNOT stand by itself), and a dependent clause. You can tell this because if I were to walk into a room and say, "When K and C read the same foldable....", you would be waiting to hear the rest, wouldn't you? A compound sentence has two independent clauses joined by a comma and a coordinating conjunction (but, and, for, nor, or, so, yet). A simple sentence is just an independent clause.
Not really a question, but that means the water would have a mass/weight of 0.29 kg
Hope that helped! Good luck!
