they get it from the things they eat
9.991 Moles (water) 8.982 Moles (heavy water)
95,474 moles
The answer is 6 moles.
The ratio of moles of CuSO4 to moles of water in CuSO4•5H2O is 1:5. This is because there is one mole of CuSO4 for every five moles of water in the compound.
3.2 moles of water (H2O)
180 grams of water is 10 moles of water.
2.95 mole H2O (2 moles H/1 mole H2O) = 5.90 moles hydrogen ------------------------------
10 moles of nitrogen dioxide are needed to react with 5,0 moles of water.
54,0 grams of water is equivalent to 3 moles.
Only when 5.5 mole O2 react with 11 mole H2, then 11 mole H2O are formed.
To calculate the moles of water, you can use the formula: moles = mass of water (in grams) / molar mass of water (about 18.015 g/mol). Simply divide the mass of water by its molar mass to find the number of moles.
The mass of 0,5 moles of water is 9 g.
