A spring scale measures weight. some even use them to measure the weight of fish
Answer:
n = 1.24 moles
Explanation:
Given that,
Mass = 153 grams
Molar mass of KClO₃ = 122.55 g/mol
We need to find the number of moles.
We know that,
No. of moles = given mass/molar mass
So,

So, there are 1.24 moles in 153 g of KClO₃.
Approximating 7 to 20 kilometers
