The density of ethanol is 0.789 g/mL. If you need 460.0 g of ethanol for an experiment, how many milliliters would you measure o
4vir4ik [10]

Answer:

The volume is 583.02 mL

Explanation:

Given that the density is:-

\rho=0.789\ g/mL

The mass, m=460.0\ g

The expression for the calculation of density is shown below as:-

\rho=\frac{m}{V}

Using the above expression to calculate the volume as:-

V=\frac{m}{\rho}

Applying the values to calculate the volume as:-

V=\frac{460.0\ g}{0.789\ g/mL}=583.02\ mL

<u>The volume is 583.02 mL.</u>

As you move from row ______ to row ______ in the periodic table, the atomic radius of the elements DECREASES.
Len [333]

Answer:

C) 7 to 1

Explanation:

The periodic trend of Atomic Radii for the Periodic Table of Elements is down and to the left the atomic radii increases.

So, from period 1 to 7 and group 18 to group 1, the atomic radii increases.

The opposite (decreasing) would be from period 7 to 1 and group 1 to group 18.

Therefore, our answer is C.
