Answer:
Jupiter and Saturn are the two biggest planets
% by mass = (mass solute/mass solution)*100%
mass of the solute = 54.7 g
mass of the solution = mass solute + mass solvent=54.7+500=554.7 g
% by mass = (54.7/554.7)*100%≈0.0986*100% = 9.86%
All atoms of a single element have the same mass
The answer would be B ur looking for the total reaction and the time that it takes for it I be produced Wich would be 6.0
