okay so first, we need to calculate the mass of the 144 pages without the cover which means: 508-220= 288. So the mass of 144 pages= 288 grams. Now, to calculate the mass of 1 page, we divide the mass of the 144 pages by the number of pages, which means: 288/144= 2 grams. The mass of one page is equal to 2 grams

Answer:

• Each page weighs 2 grams.

Step-by-step explanation:

• Let's first find the mass of book alone:


{ \rm{ = 508 \: g - 220 \: g}} \\ \\ { \underline{ \rm{ \: = 288 \: g \: }}}

• Then compare;


{ \rm{144 \: pages = 288 \: g}} \\ \\ { \rm{1 \: page = ( (1)/(144) * 288) \: g}} \\ \\ { \rm{ = 2 \: g}}
