Answer:
783 grams
Explanation:
Here mass is given in kg
Some of the prefixes of the SI units are
1 gram = 10⁻³ kilogram
1 milligram = 10⁻⁶ kilogram
1 microgram = 10⁻⁹ kilogram
1 nanogram = 10⁻¹² kilogram
The number is 0.783
Here, the only solution where the number of significant figures is three is gram. If any other prefix is chosen then the significant figures will increase
[tex]1\ kilogram = 1000\ gram[/tex]
[tex]\\\Rightarrow 0.783\ kilogram=0.783\times 1000\ gram\\ =783\ gram[/tex]
So, 0.783 kg = 783 grams
