3) How many L of gas is equal to 89.3 moles at STP?

The correct answer is 1999 l

Explanation:

We use the formula P V = nRT. The normal conditions of temperature and pressure are 273K and 1 atm, we use the gas constant = 0, 082 l atm / K mol:

1 atm x V = 0, 082 l atm / K mol  x 89, 3 mol x 273 K

V =0, 082 l atm / K mol  x 89, 3 mol x 273 K / 1 atm

V= 1999 , 06 l

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

hope it

i think   the answer is c hope i'm right
