A weather balloon filled with helium has a volume of 700 L at STP. To find the mass of helium which conversion factors would you

Vedmedyk [2.9K]

Answer:

D: (700 L / 22.4 L/mol) (4 g/mol)

Explanation:

At STP, Molar volume of a gas = 22.4 L/mol

Now, we are told that helium has a volume of 700 L at STP.

Also, atomic mass of helium = 4 g/mol

Thus, the mass of helium is given as;

(700 L/22.4 L/mol) × 4 g/mol

Which scenario would result in a population growth of zero? Use this formula: population growth = (birth rate + immigration) – (

swat32

Answer:

12 individuals are born 10 individuals emigrate, 4 individuals die, 14 individuals immigrate, 0 individuals are born

Explanation:

From the formula:

Population growth = (birth rate + immigration) – (death rate + emigration)

= (b + i) - (d + e)

For the first option, b = 12, i = 0, d = 12, e = 12

population growth = (12+0) - (12+12) = -12

For the second option: b = 13, i = 0, d = 3, e = 16

population growth = (13+0) - (3+16) = -6

For the third option: b = 12, i = 20, d = 0, e = 8

population growth = (12+20) - (0+8) = 24

For the last option: b = 0, i = 14, d = 4, e = 10

population growth = (0+14) - (4+10) = 0

Hence, the last option is the correct option.
