Answer:

The answer is

<h2>0.307 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}

From the question

mass of box is 345 g

volume = 1125 cm³

The density of the object is

density =  \frac{345}{1125}  \\  = 0.3066666...

We have the final answer as

<h3>0.307 g/cm³</h3>

Hope this helps you

Rainbow [258]
1) <span>NaNO3 and H2O - no reaction , it is dissolution
2) no hydrogen to make water
3) </span><span>Fe(OH)3 (base) and H2SO4(acid)) 
base +acid ----> salt +water
4) </span><span>Li2O and Ba(OH)2
basic oxide and base ----> no reaction

so Answer number 3)
</span> 2Fe(OH)3 +3 H2SO4 ------>   Fe2(SO4)3 + 6H2O<span>
