I have a solution to a similar problem here but different given values.
Answer:
0.409 g
Explanation:
As stated, 1 mole of NaCl weighs 58.44 g.
A 0.02 M solution contains 0.02 moles per liter.
Hence, 1 litre would contain:
58.44 x 0.02 = 1.1688 g
However, there are only 350 ml, which is 0.35 liters.
Therefore, there would be 0.35 x 1.1688 g in total, 0.409 g
Answer:
<h2>10 L</h2>
Explanation:
The new volume can be found by using the formula for Boyle's law which is
From the question we have
From the question we have
We have the final answer as
<h3>10 L</h3>
hope this helps you
Hey there!:
Number of moles = 3.33 moles of neon
Volume = 13.4 L
Pressure = 3 atm
R = 0.0821 L.atm/mol*K
Therefore:
T = 3.0 * 13.4 / 3.33 * 0.0821
T = 40.2 / 0.2734
T = 147 K
k in C :
ºC = K - 273
147 - 273
T = - 126ºC
Hope that helps!
Reaction type : Double-Replacement reactions
<h3>Further explanation</h3>
Given
Reaction
MgCl2 +
Li2CO3 →
MgCO3 +
LiCl
Required
Balanced equation
Reaction type
Solution
Balanced equation
Li2CO3 (s) + MgCl2 (aq) → MgCO3 (s) + 2 LiCl (aq)
Double-Replacement reactions. Happens if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product
To predict whether this reaction can occur or not is one of them, the precipitation reaction.
MgCO3 is a precipitation compound
