Answer:
<h2>Density = 12.5 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 52.5 g
volume = 4.2 mL
Substitute the values into the above formula and solve for the density
We have
We have the final answer as
<h3>Density = 12.5 g/mL</h3>
Hope this helps you
Ma = 1.66 M
Va = 30.7 mL
Mb = 0.704 M
Vb = 16.7 mL
Using the law <span>of dilution :
</span>
Mf = Ma x Va + Mb x Vb / Va + Vb
Mf = 1.66 x 30.7 + 0.704 x 16.7 / 30.7 + 16.7
Mf = 50.962 + 11.7568 / 47.4
Mf = 62.7188 / 47.4
Mf = 1.323 M
hope this helps!
Answer:
Explanation:
Mole = no. Molecules/6.02×10^23
Mole = (1.40×10^24)/(6.02×10^23)
Mole = 2.33mole
