solution of ammonium Sulphate fertilizer was to be applied to the soil before planting some seeds. A given volume of water was put in a large container and 3.68 kg of fertilizer was dissolved in it. On analysis, 0.28 dm3 of 0.35 mol dm-3 barium chloride was required to precipitate all the sulphate in 0.20 dm3 of solution. What was the volume of the solution in the

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

i believe it is 40–40–20%

explanation:

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

will have a gram-molecular weight of 352g.
