Answer:
1. 1.26823082 mL
2. 0.5 g/mL
Explanation:
The density formula is:
1.
Rearrange the density formula for v,
<em>Multiply both sides by v.</em>
<em>Divide both sides by d.</em>
Volume is found by dividing mass by density. The mass is 20 grams and the density is 15.77 grams per milliliter.
Substitute the values into the formula.
Divide. Note the grams, g, will cancel.
2.
Use the density formula.
Density is found by dividing mass by volume. The mass is 10 grams and the volume is 20 milliliters.
Substitute the values into the formula.
Divide.
