A protein 'A' contains 0.30% of glycine (molecular weight 75). The minimum molar mass of the protein 'A' is __________ $\times$ 103 g mol$-$1 [nearest integer]
Answer (integer)
25
Solution
<p>Let, molar mass of protein A = x</p>
<p>Protein A contains 0.30% glycine</p>
<p>$\therefore$ ${{x \times 0.3} \over {100}} = 75$</p>
<p>$\Rightarrow$ x = 25000 = 25 $\times$ 10<sup>3</sup></p>
