Someone please help me with this :,)

1. 1.26823082 mL

2. 0.5 g/mL

Explanation:

The density formula is:

1.

Rearrange the density formula for v,

                    Multiply both sides by v.

                            Divide both sides by d.

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.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
