A certain chemical reaction experiences a 7.50 × 10-7 kilogram loss in mass. If this mass were to be totally converted to energy, what would be the magnitude of that energy? (1 J = 1 kg times m squared over s squared )

1.20 × 1023 J

2.5 × 109 J

4.00 × 101 J

6.75 × 1010 J

@Abmon98  do you get it I was thinking it was B but I may be wrong ?

anonymous · Answer

are u there @Abmon98  please I need you help

abmon98 · Answer

@veronica.montanez i am trying but i dont quite get the m^2/s^2 part

anonymous · Answer

isn't it like e=mc^2 or no

abmon98 · Answer

(m/s)^2=m^2/s^2 oh yes you are right

anonymous · Answer

so how would I do that

abmon98 · Answer

E=( 7.50 × 10-7)(3.00*10^8)^2

abmon98 · Answer

10^-7**

anonymous · Answer

is that for the 3.00

abmon98 · Answer

no for the 7.50

anonymous · Answer

ok its D and I need you help on three more is that ok :) ?

abmon98 · Answer

i got Energy as 67500000000 so its a D

abmon98 · Answer

okay sure but i have to do something now i be right back in 15 minutes .

anonymous · Answer

ok  @Abmon98
