It increases by a factor of eight

Explanation:

When temperature is held constant, gas pressure changes according the volume, in undirectly proportion.

Volume increases → Pressure decreases

Volume decreases → Pressure increases

As volume gas, was reducted from 4L to 0.5L, it was reduced by 1/8, so the pressure gas was increased by a factor of eight.

Maurinko [17]

<u>Answer:</u> The correct option is b) 600

<u>Explanation:</u>

Molecules are formed when two atoms of same or different elements combine together.

Atoms are the smallest unit of matter that combines to form a compound.

For the given chemical compound, $CH_3CO_2H$

Given number of molecules = 300 molecules

In 1 mole of the given chemical compound, there are 2 atoms of carbon, 4 atoms of hydrogen and 2 atoms of oxygen

Number of atoms of oxygen = $2\times \text{Number of molecules of compound}$

Number of atoms of oxygen = $2\times 300=600atoms$

Hence, the correct option is b) 600
