2 g/cm³ is the density of the block of wood
Explanation:
To determine density of the block of wood we use the following formula:
density = mass / volume
density of the wood block = 100 g / 50 cm³
density of the wood block = 2 g/cm³

The electrons are what determines the energy level and reaction of the valence shell, hope it helps ❤️✌️
Mass of the water : 2.23 g
<h3>Furter explanation</h3>
Heat
Q = m.c.Δt
m= mass, g
c = heat capacity, for water : 4.18 J/g° C.
ΔT = temperature
Q= 140 J
Δt = 75 - 60 = 15
mass of the water :
Answer:
WOT in the world is this?
Explanation:
Answer:
696g
Explanation:
To determine the mass of ethylbutanoate produced, it is important that we know the number of moles of ethylbutanoate produced.
Now from the chemical equation, it can be seen that one mole of ethanol produces one mole of ethylbutanoate. This means that 6.0 mol of ethanol will surely produce 6.0 mol of ethylbutanoate.
Now, we need to get the mass of ethylbutanoate produced. The mass of ethylbutanoate produced is the number of moles of ethylbutanoate produced multiplied by the molar mass of ethylbutanoate produced.
The molar mass of ethylbutanoate is 12(6) + 12(1) + 16(2) = 116g/mol
The mass thus produced is 116 * 6 = 696g
