Calculate the mass of water obtained by combustion in oxygen of hydrogen with an amount of 0.6 mol. Chemical reaction equation: 2H2 + O2 = 2H2O
It is necessary to calculate the mass of water M obtained by combustion in oxygen of hydrogen, the amount of substance being 0.6 mol.
To solve this problem, it is necessary from the formula for the combustion of hydrogen in oxygen to calculate how many moles of water there are per mole of hydrogen.
2H2 + O2 = 2H2O.
For two moles of hydrogen 2 * 0.002 kg, there are two moles of water 2 * 0.018 kg.
From here you can find the mass of water, when burning 0.6 mol of hydrogen. Multiply the number of moles by the molar mass of water.
M = 0.6 mol * 0.018 kg = 0.0108 kg.
