One mole of sodium sulfate is 143.04, so just multiply that times 6.31.
I may be wrong call me out if I am
C2H2, or acetylene, has a molar mass of 26g. That means it has 113/26 = around 4.34 mols. Assuming complete combustion, the balanced equation comes out to this:
C2H2 + 3O2 --> 2H2O + 2CO2
Using the molar ratios, we get that we get 8.68 mols of water for every 4.34 mols, so since the molar mass of water is 18 grams per mol, we multiply 18 * 8.68 = about 156.24 grams.
If you mean STEM, S is science, T is technology, and M is math.
This dome-like shape forms due to the water molecules' cohesive properties, or their tendency to stick to one another. ... Water molecules at the surface (at the water-air interface) will form hydrogen bonds with their neighbors, just like water molecules deeper within the liquid.
