A student gains 1.0 lb in two weeks. How many grams did he gain?
Express your answer to two significant figures and include the appropriate units.





I don’t know

Respuesta :

1 lb=453.592 grams
So he gained 453.592 pounds
1lb= 453.592g but then to change to 2 significant figures you go down two of the numbers so here it will be 4 and 5 that stands for 450g. So he gained 450g. I hope that helped
