Answer:
i would assume that it would be (a)
Explanation:
The Sun generates its energy by nuclear fusion
NUCLEAR FISSION is when the heavy atom is split
fusion energy is scientifically feasible. Plasma conditions that are very close to those required in a fusion reactor are now routinely reached in experiments
mass gets lost is nuclear fusion
so (a) is the most accurate
Answer:
<h2>251 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 0.251 × 1000
We have the final answer as
<h3>251 g</h3>
Hope this helps you
It has many different uses like being used to make the tube of a vacuum cleaner and also can be used to make oil in space crafts.
1 mole of NaCl has (23+35.5)g= 58.5g
Therefore, to make 1M/L of solution you will need 58.5g Then to make 0.5M/L you will need 58.5/2=29.25g
If to make 1liter of 0.5M one will need 29.25 grams of NaCl, then250g of NaCl will make
(250g×1L)/29.25g= 8.547liters
