Answer:
The mass will be recorded upto 5 significant figures.
Step-by-step explanation:
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
Mass of the object = 5 g = 5000 mg
1 gram = 1000 milligrams
Accuracy of the analytical weighing balance = 0.1 mg
So, the mass of the object when placed on analytical weighing balance = 5000.0 mg
Number of significant figures in 5000.0 = 5 significant figures
(All zero’s after the decimal point are always significant)
The mass will be recorded upto 5 significant figures.
Should be recorded as 5000.0 mg which is 5 significant figures.
This is based on conversion of units and approximation to significant figures.
- We are told that the object has a mass of exactly 5g. Converting this to mg gives; 5000 mg.
- Now, we see that the analytical balance used to weigh it has an accuracy of 0.1 mg. Since the analytical balance is accurate to within 0.1 mg, this means that any proper weighing done with it will be accurate to that 0.1 mg level.
That means to the nearest 0.1 mg, we can write the weight s 5000.0 mg which is 5 significant figures because 0 is also a significant figure.
