An object has a density of 1.75 g/mL. Will it float on water? Why?
Advocard [28]

Answer:

The object will not float in water because the density of the object is greater than that of water.

Explanation:

Density of object = 1.75 g/mL

Density of water = 1 g/mL

The Density of the object is 1.75 g/mL and that of water is 1 g/mL. This implies that the object is denser (i.e heavier) than water. Therefore, the object will not float in water, rather it will sink in water since it's density is greater than that of water.

What is the density of a 6.0 × 102 mL liquid sample that weighs 450 g?
mart [117]

Answer:

<h2>Density = 0.75 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

Density =  \frac{mass}{volume}

From the question

mass = 450 g

volume = 6.0 × 10² mL

Substitute the values into the above formula and solve for the density

That's

Density =  \frac{450}{6 \times  {10}^{2} }  =  \frac{450}{6 00}  \\  =  \frac{3}{4}

We have the final answer as

<h3>Density = 0.75 g/mL</h3>

Hope this helps you
