Astudent is asked to convert measurements from grams to kilograms and from kilograms to grams. his answers are shown in bold in the choices shown below. on which choice did he make a mistake? 765 g = 0.765 kg 10.1 g = 0.0011 kg 1000 g = 1 kg 5.44 g = 0.00544 kg

10.1 g = 0.0011 kg is incorrect

Explanation:

When converting from g to kg we divide by 1000 and when converting from kg to g we multiply by 1000.

765 g = 0.765 kg is correct since 1 kg = 1000 g  

10.1 g = 0.0011 kg is incorrect since 1 kg = 1000 g

10.1 g = 0.0101 kg is correct

1000 g = 1 kg is the correct conversion factor

5.44 g = 0.00544 kg is correct since 1 kg = 1000 g

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
