Answer: 48800g
Explanation:
Using the mathematical relation : Moles = Mass / Molar Mass
Moles = 488
Molar mass of CaCO3 = 40 + 12 + (16 x 3) = 100g/mol
Therefore
488 = mass / 100 = 48800g
Balance Chemical Equation is as follow,
<span> Cu + 2 AgNO</span>₃ → 2 Ag + Cu(NO₃)₂
According to Balance Equation,
2 Moles of Ag is produced by reacting = 1 Mole of Cu
So,
0.854 Moles of Ag will be produced by reacting = X Moles of Cu
Solving for X,
X = (0.854 mol × 1 mol) ÷ 2 mol
X = 0.427 Moles of Cu
Result:
0.854 Moles of Ag are produced by reacting 0.427 Moles of Cu.
The sun makes the moisture go into the air and evaporate
Answer:
The answer is
<h2>13.84 %</h2>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual volume = 22.4 L
error = 22.4 - 19.3 = 3.1
The percentage error is
We have the final answer as
<h3>13.84 %</h3>
