JEE MAIN - Chemistry (2022 - 25th June Evening Shift - No. 16)
A protein 'A' contains 0.30% of glycine (molecular weight 75). The minimum molar mass of the protein 'A' is __________ $$\times$$ 103 g mol$$-$$1 [nearest integer]
Answer
25
Explanation
Let, molar mass of protein A = x
Protein A contains 0.30% glycine
$$\therefore$$ $${{x \times 0.3} \over {100}} = 75$$
$$\Rightarrow$$ x = 25000 = 25 $$\times$$ 103
