Answer: 85.62 L represents volume (V).
Explanation:
Volume is defined as the amount or quantity of a given substance or an object.
According to ideal gas equation:

P = pressure of gas = 4.95 atm
V = Volume of gas = 85.62 L
n = number of moles
R = gas constant =
T =temperature =
Thus 85.62 L represents volume (V).

Answer:</h3>
Mole ratio of D to A is 1 : 4
<h3>
Explanation:</h3>
We are given the generic chemical equation;
4A + B → C + D
We are supposed to determine the mole ratio of D to A
What is mole ratio?
- Mole ratio is the ratio of the number of moles of reactants or products in a chemical reaction.
- We determine the mole ratio using the coefficients of reactants or products in question.
For example;
- In the equation, 4A + B → C + D, the coefficient of A is 4 while the coefficient of D is 1.
- This means, 4 moles of A reacts with 1 mole of b to produce 1 mole of C and 1 mole of D
- Thus, mole ratio of D to A is 1 : 4
