If a 10mL object has a density of 1.5g/mL, what would its mass be (in g)?
kakasveta [241]

Answer:

15 g

Explanation:

The density of an object can be found using the following formula:

d=\frac{m}{v}

We want to find the mass, so we must rearrange the formula for m. Multiply both sides of the formula by v.

d*v=\frac{m}{v}*v

d*v=m

The mass can be found by multiplying the density and volume.

The density of the object is 1.5 g/mL and the volume is 10 mL.

d=1.5 g/mL \\v=10 mL

Substitute the values into the formula.

m=d*v

m=1.5 g/mL * 10 mL

Multiply. When multiplying, the milliliters, or mL will cancel out.

m= 1.5 g*10

m=15 g

The mass of the object is 15 grams.

alexdok [17]

Hello. You forgot to add the diagram.

The diagram is attached below.

Answer:

1. examination of homologous fossilized structures of primitive horses

Explanation:

As you can see in the diagram, to show the stages of the development of the modern horse, a comparison is made between the forelimb structure and the molar tooth of these horses (related to the adult form). These two factors of comparison establish the representation of fossilized homologous structures of primitive horses.

As you may already know, homologous structures are different body structures from different animals that have a strong similarity (because they are inherited from a common ancestor). When these animals die and these structures are conserved, we can say that they have been fossilized.

As the forelimb structure and the molar tooth of the horses shown in the diagram are homologous structures that were fossilized, we can say that option 1 is the correct answer to your question.
