Answer:
2.41 g of NaCl is needed
Explanation:
Molarity of solution = (Number of moles of solute)/(Volume of solution in Litre)
Here sodium chloride (NaCl) is solute in saline solution
275 mL = 0.275 L
So, number of moles of NaCl in 275 mL saline solution =
Molar mass of NaCl = 58.44 g/mol
Number of moles = (mass)/(molar mass)
So, mass of 0.04125 moles of NaCl =
So, 2.41 g of NaCl is needed
Answer:
3.
Explanation:
- Al(OH)₃ reacts with HCl to produce AlCl₃ and water according to the balanced equation:
<em>Al(OH)₃ + 3 HCl → AlCl₃ + 3H₂O,</em>
<em></em>
<em>It is clear that 1.0 mole of Al(OH)₃ reacts with 3.0 mole of HCl to produce 1.0 mole of AlCl₃ and 3.0 moles of H₂O,</em>
<em />
<em>So, the coefficient of HCl is 3.</em>

Answer:
A.
Explanation:
I forgot butt im surely it is;-)
defined, a solid will always have a definite shape and volume because it doesn´t depend on its container shape
