A protein ‘A’ contains 0.30% of glycine (molecular weight 75). The minimum molar  of the protein ‘A’ is_______$x\times {10}^{3}gmo{l}^{-1}$  what is  $\frac{x}{3}$[Rounding to nearest integer]

0.3 % glycine means 
100g protein ‘A’ contains 0.3g glycine.
Since, molar mass of glycine is 75
75g glycine will be present in $\frac{100}{0.3}\times 75$ g protein
Minimum molar mass of protein A is $25\times {10}^{3}g/mol$
