Hey there!:
Density = 0.798 g/mL
Volume = 16.9 mL
Therefore:
Mass = density * volume
Mass = 0.798 * 16.9
Mass = 13.4862 g
<h3>1.Option B</h3><h3>Elements can be defined as pure substances that are made up of only single type of atom. </h3>
<h2>Note:</h2>
- Single type of atom not single atom
<h3>2.Option B </h3><h3>Aluminum foil is correct because heterogenous mixtures are uniform throughout the mixture. and foil is uniform but other option given are not uniform.</h3>
I think the answer is atoms.
<span>Acetone has a density of 784 kg/mÂł (this you can look up).
This equals 784.000 g/mÂł (kilo means 1000).
Which can be converted to 0.784 g/cm3 (1 m3 is 1.000.000 cm3).
A cm3 is exactly 1 ml. So 0.784 g/cm3 = 0.784 g/ml.
We have 6.68 gram of acetone. 6.68 g / 0.784 g/ml = 8.52 ml.
So the volume of 6.68 grams of acetone is 8.52 ml.</span>
