The answer is force=6, time=3, so C is correct
Here, Equation: 2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O
We know, Concentration (c) = Number of moles(n) / Volume (v)
Substitute the given values,
0.02 = n / 0.3 [ 300 mL = 0.3 L ]
n = 0.3 * 0.02
n = 0.006
Now, According to stoichiometry, There is 1 Molecule of Sodium sulfate produces for every 2 molecules of NaOH.
So, Number of Moles of Na₂SO₄ = 0.006/2 = 0.003
Given mass = Molar mass * Number of moles
M = 142.04 * 0.003
M = 0.426 g
In short, Your Answer would be: 0.426 g
Hope this helps!
Answer:
Explanation:
The specific heat of a substance is the amount of heat required to the raise the temperature of a unit mass of substance by 1°C.
This physical quantity is usually determined in the laboratory. It is an intensive property of substances and a constant for pure samples of material.
Specific heat for the steel wire 0.82J/g°C
specific heat for the steel wire 0.47J/g°C
specific heat for the lead pellets 0.25J/g°C
