Answer:
0.4
Explanation:
Given data:
Number of moles of SrCl₂ consumed = ?
Mass of ZnCl₂ produced = 54 g
Solution:
Chemical equation:
ZnSO₄ + SrCl₂ → SrSO₄ + ZnCl₂
Number of moles of ZnCl₂:
Number of moles = mass/ molar mass
Number of moles = 54 g/136.3 g/mol
Number of moles = 0.4 mol
Now we will compare the moles of ZnCl₂ with SrCl₂ from balance chemical equation.
ZnCl₂ : SrCl₂
1 : 1
0.4 : 0.4
Thus when 54 g of ZnCl₂ produced 0.4 moles of SrCl₂ react.

Answer:</h3>
A. 860 kg
<h3>
Explanation:</h3>
To answer the question we need to understand that;
- Mass refers to the amount of matter in an object.
- Weight, on the other hand, refers to the gravitational pull of an object to a given surface.
- Mass is measured using a spring balance.
We also need to know that;
- The mass of an object remains constant every where irrespective of the gravitational acceleration.
- Therefore, an object on the surface of the earth would have the same mass as on the surface of the moon.
- In this case; the mass of the car remains the same on the outer space as on the back yard.
