STEP 2 : Calculate the number of grams in 1.3 pound.

Multiply the number by 1.3

1.3 pound = 1.3 x 453.6  grams

1.3 pound = 589.68 grams

STEP 3: Calculate the mass in 20 % percentage of sample.

$20\% of\ x=x\times \frac{20}{100}$

Here x = 589.68 grams

$20\%\ of\ 589.68 =589.68\times \frac{20}{100}$

$20\%\ of\ 589.68 =117.93grams$

= 117.94 grams
