In 1 lb there are 450 grams (Rounded upto 2 - Significant figures).
We havea weight gain of 1.0 lb.
We have to convert it into grams.
I lb = 453.592 grams
According to the question -
A = 1 lb
Converting it into grams, we get -
1 lb = 1 x 453,592 = 453.592 grams
Rounding up to 2 - Significant figures, we get -
1 lb = 450 grams
Hence, in 1 lb there are 450 grams (Rounded upto 2 - Significant figures).
