Can someone answer these plss :-))) 1. You have sample of 269.16 grams of water which contains 29.91 g of Hydrogen and 239.25 g of Oxygen.

Calculate the % Composition of H and O.

What is the mass ratio of this sample of water?

2. A sample of 150.00 grams of NaCl is composed of 60.00 g of Na and 90.00 g of Cl

Calculate the % Composition of Na and Cl

Calculate the mass ratio of your sample

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.
