Use equation density = mass/volume
Known/Given
d= 10.5g/cm^3
v= 24.0 cm^3
Use that equation i just mentioned...
Solution
Rewrite the formula as the forumla for solving density into mass
Which is... mass = 10.5g/cm^3 × 24.0cm^3 = 252g
So thats the answer
252g
Hope i could help
Answer:
D
Explanation:
Any change of temperature will subsequent in a change of the equilibrium position. With reference to Le Chaterlier's principle, this equilibrium shift will occur in a manner as to <em>neutralize the change</em> that the system has undergone.
In this case, the temperature is seen to have decreased. To neutralize this effect, the equilibrium position will <em>shift </em>in a manner as to <u>increase</u> the temperature back to its previous state.
This equilibrium shift will occur by favoring the reaction the reaction which results in the release of heat -which is the formation of dinitrogen tetrahydroxide.
This will result in the presence of more dinitrogren tetrahydroxide relative to the amount of nitrogen dioxide in the system.

C6H12O6
Explanation:
Just use the table method like I did and compared the molecular mass with the mass of the empirical formula.
Answer:
Explanation:
Hello,
In this case, given the balanced reaction:
We can see a 2:4 mole ration between permanganate ion (118.9 g/mol) and manganese (IV) oxide (86.9 g/mol), that is why the resulting mas of this last one turns out:
