Answer: B. 448.0 moles
Explanation:
The balanced chemical equation is :
According to stoichiometry :
3 moles of produce = 1 mole of
Thus 48.00 moles of will produce = of
Mass of
Thus 448.0 g of will be produced from 48.00 moles of NaOH.
The vertical component of velocity is zero
Explanation:
You have a solution that contains 36 g HCl dissolved in 64 g water
Molar mass HCl = 36.45 g/mol
Mol HCl in 36 g = 36 g / 36.45 g/mol = 0.9876 mol
Molar mass H2O = 18 g/mol
Mol H2O in 64 g = 64 g / 18 g/mol = 3.5556 mol
Total mol = 0.9875 + 3.5556 = 4.5431 mol
Mol fraction HCl = 0.9876 mol / 4.5431 mol = 0.2174
Mol fraction H2O = 3.5556 / 4.5431 = 0.7826
The answer should have 2 significant digits:
Mol fraction HCl = 0.22
Mol fraction H2O = 0.78
Mol fraction has no units.
THAT IS HELPFUL FOR YOU
