What is the mass of 0.100 mole of neon? (Watch sf’s) 2.018 g 20.18 g 2.02 g 2 g
makkiz [27]

Answer:

The mass of 0.100 mole of neon is 2.018 grams.

Explanation:

As we know the formula to find mass:

                           Number of moles         =  Mass/ Molar mass

                                        0.100                = Mass/ 20.17

                                        0.100 x 20.17   = Mass

                                                        Mass=2.018 grams.

Hope it helps!

Question 3 (please help)
poizon [28]

Answer:

the Answer is B

Explanation:

If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size. Every stable population has one or more factors that limit its growth. A limiting factor determines the carrying capacity for a species.

hope this helps have a good day :)

Aluminum has a density of 2.70 g/ cm3. What volume is occupied by a block of aluminum which weighs 4.32 kg?
Ray Of Light [21]

Answer:

1600cm3

Explanation:

From the question given, we obtained the following:

Density = 2.70g/cm3

Mass = 4.32kg :we need to convert the mass to grams

Mass = 4.32kg = 4.32 x 1000 = 4320g

Volume =?

Recall : Density = Mass /volume

Volume = Mass /Density

Volume = 4320/2.70

Volume = 1600cm3

What is the chemical formula for a compound between Al and F? AlF AlF 3 AlF 2 Al 3F
tester [92]

Answer:

AlF3

Explanation:

Aluminum fluoride (AlF3) is an inorganic compound in which aluminum and fluoride has ionic bond between each other.

Aluminum ( atomic number - 13) has 3 valence electrons and can lose 3 electrons to get a stable configuration while fluorine (atomic number - 9) can gain one electron to make a stable configuration. So in order to attain a stable configuration one aluminum (Al) atom form ionic bond with three fluorine atoms and form AlF3.

Hence, the chemical formula between  Al and F is AlF3.
