Question

If you have 134.4 L of a gas then how many moles do you have?
a. 6 moles
b. 3 moles
c. 7 moles
d. 9 moles

Answer 1

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

Let's solve ~

$\qquad \sf  \dashrightarrow \: 22.4 \: L = 1 \: mole$

$\qquad \sf  \dashrightarrow \:1 \: L = \dfrac{1}{22.4} \: mole$

$\qquad \sf  \dashrightarrow \: 134.4 \: L = \dfrac{1}{22.4} \times 134.4 \: moles$

$\qquad \sf  \dashrightarrow \: 134.4 \: L = 6 \: moles$

Therefore, correct choice is A.)
