How many liters of CH4 gas are there in 1.20 moles of CH4 when the gas is held under standard conditions? Please answer quickly!

26.88 L

Explanation:

When any gas is held under standard conditions, one mol will occupy 22.4 liters.

With the above information in mind, we can calculate how many liters would 1.20 moles of CH₄ gas occupy under standard conditions:

1.20 mol * 22.4 L/mol = 26.88 L

So 1.20 moles of CH₄ would occupy 26.88 liters.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

16
