Answer:
2.9 g
Explanation:
There is some info missing. I think this is the original question.
<em>Ammonium perchlorate is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas, chlorine gas, oxygen gas, water, and a great deal of energy.
</em>
<em>What mass of water is produced by the reaction of </em><em>9.6 g</em><em> of ammonium perchlorate?</em>
<em />
Step 1: Given data
Mass of ammonium perchlorate: 9.6 g
Step 2: Write the balanced equation
2 NH₄ClO₄(s) → N₂(g) + Cl₂(g) + 2 O₂(g) + 4 H₂O(l)
Step 3: Calculate the moles corresponding to 9.6 g of ammonium perchlorate
The molar mass of ammonium perchlorate is 117.49 g/mol.

Step 4: Calculate the moles of water formed from 0.082 moles of ammonium perchlorate
The molar ratio of NH₄ClO₄ to H₂O is 2:4. The moles of water formed are 4/2 × 0.082 mol = 0.16 mol
Step 5: Calculate the mass corresponding to 0.16 moles of water
The molar mass of water is 18.02 g/mol.

.. it’s the answer 0.25 g MgSO4? ..
I may be wrong.
Answer:
Explanation:
The fundamental units of a measurement is known as its base unit. The units of these substances serves as the base through which other quantities depends. Examples of such quantities are mass, length, time, electric current, temperature, amount of substance and luminous intensity.
Derived units are those that results from the combination of the fundamental or basic units. Examples of derived quantities are force, volume, density, pressure e.t.c.
Derived units of Density:
kgm⁻³
gcm⁻³
Derived unit of volume:
m³
cm³
mL
L
dm³
