Answer:
If space you space take space 1.2 percent sign space NaCl space and space 7.2 percent sign space glucose space then space you space wll space get space answer space as space 2.

For space isotonic space solutions

fraction numerator straight w subscript 1 over denominator straight M subscript 1 cross times straight V subscript 1 end fraction equals fraction numerator straight w subscript 2 over denominator straight M subscript 2 cross times straight V subscript 2 end fraction

space space space space space space space space straight w subscript 1 over straight M subscript 1 equals straight w subscript 2 over straight M subscript 2

space fraction numerator 1.2 over denominator 100 cross times straight M subscript 1 end fraction space equals space fraction numerator 7.2 over denominator 100 cross times 180 end fraction

space space space space space space space space space space space space space straight M subscript 1 space space equals space 30 space straight g divided by mol

van apostrophe straight t space Hoff apostrophe straight s space factor space comma space straight i space equals fraction numerator Calculated space mass over denominator Observed space mass end fraction space space space space space space space space

space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals fraction numerator 58.4 over denominator 30 end fraction space space space

space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 1.95

space space space space space space space space space space space space space space space space space space space space space space space space space space space space space straight i space space approximately equal to space 2
