Answer: 24.1 L of 2.27 M HF will react with 3.70 kg of
Explanation:
The balanced chemical reaction :
To calculate the number of moles, we use the equation:
According to stoichiometry :
1 mole of require = 4 moles of
Thus 13.7 moles of will require= of
To calculate the volume for given molarity, we use the equation:
.....(1)
Molarity of solution = 2.27 M
Volume of solution in L= ?
Putting values in equation 1, we get:
Thus 24.1 L of 2.27 M HF will react with 3.70 kg of
Answer:
0.57 mol/L
Explanation:
Molarity (M) is defined as the number of moles of solute per liter of solution (moles/Liter).
Molarity = or Moles = molarity × litres
so, the mass of Nacl in 1 mol is 58.44 g,
Moles of NaCl = 50.0g x 1 mole NaCl / 58.44 g
= 0.855 mol NaCl
Moles = molarity × litres
0.855 = 1.5 M x L
L = 0.57 mol/L
Hence, 0.57 mol/L can be prepared from 50.0 g of NaCl.
