% m/v of the solution = 0.2%m/v
<h3>Further explanation</h3>
![\tt Percent~m/v=\dfrac{mass~solute(g)}{volume~solution(ml)}\times 100\%](https://tex.z-dn.net/?f=%5Ctt%20Percent~m%2Fv%3D%5Cdfrac%7Bmass~solute%28g%29%7D%7Bvolume~solution%28ml%29%7D%5Ctimes%20100%5C%25)
or
% m/v = g solute / 100 ml solution
Concentration : 2 g sodium borate / L water
For 10 L⇒20 g Sodium borate

Answer:
0.208mole of CO2
Explanation:
First, let us calculate the number of mole of HC3H3O2 present.
Molarity of HC3H3O2 = 0.833 mol/L
Volume = 25 mL = 25/100 = 0.25L
Mole =?
Mole = Molarity x Volume
Mole = 0.833 x 0.25
Mole of HC3H3O2 = 0.208mole
Now, we can easily find the number of mole of CO2 produce by doing the following:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
From the equation,
1mole of HC2H3O2 produced 1 mole of CO2.
Therefore, 0.208mole of HC2H3O2 will also produce 0.208mole of CO2
Answer:
Theory of Plate Tectonics
Explanation:
Scientists especially Geologists study and record seismic data and volcanic activities in order to support the theory of plate tectonics.
The theory of plate tectonics suggests that the earth is broken into slabs called the lithosphere that moves over the fluid asthenosphere below.
- The use of seismic data presents scientists with a way of vertically looking deep into the earth.
- Volcanic activities also presents us with the kind of materials down within the earth.
- Also, coupled with this data, scientists use GPS sensors to monitor the rate of movement of the earth.
- When studying plate tectonics, it invariably culminates in the study of sea floor spreading and theory of continental drift.
Answer:
The answer is 375.54 g of AgBr
Explanation:
Mass (g) = Concentration (mol/L) x volume (L) x Molecular Weight of AgBr (g/mol)
Mass = 2M x 1L x 187.77 g/mol
Mass = 375.54g
Answer:
Assuming it was collected from the atmosphere it would be virtually nothing
Explanation:
hydrogen makes up 0.000055% of the atmosphere while oxygen makes up 23 percent. 20/400000 cm^3 of hydrogen
