Expert Answer:

begin mathsize 14px style We space know space that space specific space gravity space of space liquid space equals fraction numerator Loss space of space weight space of space body space in space liquid over denominator Loss space of space weight space of space body space in space water end fraction Given space weight space of space body space in space air space straight W subscript straight a space equals space 50 space straight g Weight space of space body space space in space water comma space straight W subscript straight w space equals space 40 space straight g Let space straight W subscript straight l space be space the space weight space of space the space body space in space liquid. Therefore space we space have comma 1.5 space equals fraction numerator straight W subscript straight a minus straight W subscript straight l over denominator straight W subscript straight a minus straight W subscript straight w end fraction 1.5 space equals fraction numerator 50 minus straight W subscript straight l over denominator 50 minus 40 end fraction 1.5 cross times 10 space equals space 50 space minus straight W subscript straight l rightwards double arrow straight W subscript straight l space equals space 50 space minus space 15 straight W subscript straight l space equals space 35 space straight g Hence space the space weight space of space the space body space in space liquid space of space specific space gravity space 1.5 space equals space 35 space gram end style
