The answer is A. Gas particles!
<span>To calculate the density of a liquid, you have to first know that density is the amount of substance per unit of volume. In this specific question, density will be found with units of g/mL. Now, the density can be found by dividing the amount of liquid, 75.0g, by the volume, 62.4mL. Doing this we get: 75.0g/62.4mL= 1.2 g/mL as the density of the liquid.</span>
1 kg ----------------- 1000000 mg
0.00576 kg -------- ??
0.00576 x 1000000 / 1 => 5760 mg
