Object is irregularly shaped solid and it is dropped into a graduated cylinder and it displays 25 mL of water and has a mass of
Blababa [14]

Answer:

<h2>1.2 g/mL</h2>

Explanation:

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

density =  \frac{mass}{volume}\\

From the question

mass = 30 g

volume= 25 mL

We have

density =  \frac{30}{25}  \\  = 1.2

We have the final answer as

<h3>1.2 g/mL</h3>

Hope this helps you

A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solutio
Alja [10]

Answer:

Concentration of original solution = 1.66

Explanation:

We know that

H_2SO_4+2NaOH\rightarrow Na_2SO_4+2H_2O

We have given concentration of NaOH = 0.1678

Volume of NaOH = 19.88 mL = 0.01988 L

So moles of NaOH = volume x concentration of NaOH

= 0.01988\times 0.1678=0.00333mole

Moles of H_2SO_4 in 10 mL of diluted solution = 1/2 x moles of NaOH

= \frac{1}{2} x 0.00333 = 0.00166 mol

Moles of H_2SO_4 in 25 mL of original solution

= moles of H2SO4 in 250 mL of diluted solution

= \frac{250}{10} x 0.00166 = 0.0415 mol

Concentration of original solution = \frac{moles}{volume}

= \frac{0.0415}{0.025}=1.66
