What is the orbital diagram for fluorine?

pogonyaev

Explanation:

The orbital for fluorine is 1s 2s 2p. All of the boxes should be filled COMPLETELY until you can't no more. How do you know if you can't anymore? By the <u>atomic number</u> of the element. The atomic number for fluorine is 9. So, you keep adding arrows starting from the first box all the way to the last until you have reached the atomic number, in this case, 9.

An object with a mass of 5.6 g raises the level of water in a graduated cylinder from 25.1 mL to 33.9 mL. What is the density of

kondor19780726 [428]

Answer:

0.6364 g/cm^3

Explanation:

Density = mass/volume

Where mass = 5.6g and...

Volume = (33.9 - 25.1) = 8.8ml

Where 1ml = 1 cm^3

Density = 5.6/8.8 = 0.6364 g/cm^3

Milk has a density of 1.04 g/ml. If you have a volume of 510 ml, what is the mass in grams

Law Incorporation [45]

Density is defined as the ratio of mass and volume. The formula of density is:

$density = \frac{mass}{volume}$ -(1)

Density of milk = $1.04 g/mL$ (given)

Volume of milk = $510 mL$ (given)

Substituting the values in formula (1):

$1.04 g/mL = \frac{mass}{510 mL}$

$mass= 1.04 g/mL \times 510 mL$

$mass = 530.4 g$

Hence, the mass of the milk is $530.4 g$ .
