morpeh [17]

Answer:

4.756 miles

Step-by-step explanation:

It is given that,

The running trail in the local park is 3.416 miles long. If the park board were planning to extend the trail by 1.34 miles.

We need to find the new length of the running trial. It is equal to the sum of length of running trail and the extended length. So,

l = 3.416 +1.34

l = 4.756 miles

So, the new length of the running trail be 4.756 miles

Calculate the density of benzene if 0.10L has a mass of 36.4g.

adelina 88 [10]

Answer:

$d=0.364\ g/cm^3$

Step-by-step explanation:

It is given that,

Mass of benzene, m = 0.1 L

Mass, m = 36.4 g

We know that, 1 L = 1000 cm³

0.1 L = 100 cm³

The density of an object is equal to its mass divided by its volume. So,

$\rho=\dfrac{m}{V}\\\\=\dfrac{36.4\ g}{100\ cm^3}\\\\=0.364\ g/cm^3$

So, the density of benzene is $0.364\ g/cm^3$ .
