Popcorn and salt as the mixtures are substances which are formed by mixing other substances
The crush is thicker in the ocean
1.0006 moles O2
To solve for moles to grams, you use the molar mass (from the periodic table, so for oxygen it is 15.999 grams) to solve for moles this you set up the equation like this:
Since the ethanol has a density of 0.800 g/mL, the mass of the ethanol is 180 grams.
<u>Given the following data:</u>
- Volume of ethanol = 225 mL
- Density of lead ball = 0.800 g/mL.
To find the mass of the ethanol;
Density can be defined as mass all over the volume of an object.
Mathematically, the density of a substance is given by the formula;

Making mass the subject of formula, we have;

Substituting the given parameters into the formula, we have;
<em>Mass of ethanol </em><em>=</em><em> 180 grams.</em>
