Answer:
113.8g
Explanation:
Statement of problem: mass of 1.946mole of NaCl
Given parameters:
Number of moles of NaCl = 1.946mole
Unknown: mass of NaCl
Solution
To find the mass of NaCl, we apply the concept of moles which expresses the relationship between number of moles and mass according to the equation below:
Number of moles = 
To find the molar mass of NaCl:
the atomic mass of Na = 23g
atomic mass of Cl = 35.5g
Molar mass of NaCl = (23 + 35.5) = 58.5gmol⁻¹
Mass of NaCl = Number of moles x molar mass of NaCl
Mass of NaCl = 1.946 x 58.5 = 113.8g
I Believe it would be 46.005500
hoped this helped let me know if I'm wrong
Answer:
The answer would be cation
Explanation:
Answer:
Mass = 199.21 g
Explanation:
Given data:
Moles of HCl = 3.59 mol
Mass of CaCl₂ = ?
Solution:
Chemical equation:
2HCl + Ca(OH)₂ → CaCl₂ + 2H₂O
we will compare the moles of HCl with CaCl₂ from balanced chemical equation:
HCl : CaCl₂
2 : 1
3.59 : 1/2×3.59 = 1.795
3.59 moles of HCl will produced 1.795 moles of CaCl₂.
Mass of CaCl₂.
Mass = number of moles × molar mass
Mass = 1.795 mol × 110.98 g/mol
Mass = 199.21 g
