Answer:
<h3>The answer is 0.67 cm³ </h3>
Explanation:
Density of a substance can be found by using the formula
<h3>

</h3>
Making volume the subject we have
<h3>

</h3>
From the question
mass of gold nugget = 13 g
Density = 19.3 g/cm³
Substitute the values into the above formula and solve for the volume
We have
<h3>

</h3>
= 0.673575
We have the final answer as
<h2>0.67 cm³</h2>
Hope this helps you
NaCl molar mass 58.4 g/mol
moles of NaCl = .35 g * 1 mol/58.4 g = 0.005993 mol
volume of solution = 150 mL = 0.15 L
molarity = mol/vol(in L)
[NaCl] = 0.005933mol/0.15L = 0.03995 M = 0.040 M
