Answer:
Theoretical yield of sodium chloride = 14.04 g
Explanation:
Given data:
Mass of sodium bromide = 25 g
Theoretical yield of sodium chloride = ?
Solution:
Chemical equation:
NaBr + KCl → NaCl + KBr
Number of moles sodium bromide:
Number of moles = Mass /molar mass
Number of moles = 25.0 g / 102.9 g/mol
Number of moles = 0.24 mol
Now we will compare the moles of NaCl with NaBr .
NaBr : NaCl
1 : 1
0.24 : 0.24
Theoretical yield of sodium chloride:
Mass = moles × molar mass
Mass = 0.24 mol × 58.5 g/mol
Mass = 14.04 g
Answer:
hydroxide ion
Explanation:
acids produce hydrogen ion when dissolved in water
Answer:
3.269 kg
Explanation:
1000g = 1 kg. Since kg is the larger unit, you need to divide by 1000 to get kilograms. You can do the problem as a unit conversion:
3269 g × <u>1 kg</u> = 3.269 kg
1000g
