Answer:
The amount is
Explanation:
From the question we are told that
The distance traveled per day is
The cost of one liter is
The car's gas mileage is
Generally the amount of distance covered in one week is evaluated as
The amount of gas used in one week by the car is mathematically represented as
=>
=>
converting to liters
Thus the amount spent on gas in one week is
=>
=>
24.25 moles of NO can be produced using 97 moles of HNO3.
<h3>What is balanced chemical equation?</h3>Equal numbers of atoms from various elements are present in both the reactants and the products in balanced chemical equations. Varied elements' atom counts in the reactants and products of unbalanced chemical equations are different.
3 Cu + 8HNO3 g → 3 Cu(NO3)2 + 2 NO + 4 H2O
The number of moles consumed can be calculated using comparing with coefficients in the balanced reaction .
So , from above eq we get that 8 moles of HNO3 are consumed to make 2 moles of NO.
⇒ 8 HNO3⇔2 NO
⇒ 1 HNO3⇔ 1/4 NO
This means that for each mole of HNO3 produces 1/4 moles of NO.
So , for 97 moles of HNO3 , moles of NO can be made,
So, total moles of NO made are 24.25 moles.
