Somebody help please

1. A solution that is 1% mass contains

A) 1 mole solute 1 liter of solution
B) 1 gram in 1oo gram solution
C) 1 ml of solute in 100 ml solution
D) 1 gram of solute in 1 kg of solution

which answer is it???

I also need to balance this equation but I am kinda shaky on that

C2H2 + O2 H20 + CO2

any help is appreciated

Advice: Whenever you get stuck, just pick the letter you haven't used in a minute.

I pick A.
