Insulin constans 3.4% sulphur. The minimum mol. wt. of insulin is-(1)

1.	Insulin constans 3.4% sulphur. The minimum mol. wt. of insulin is-(1) 941.176(2) 944(3) 945.27(4)
Answer» 3.4 % of Sulphur in Insulin means 3.4 g of Sulphur in 100 g of Insulin. Molar weight of Sulphur (S) = 32 g Insulin should contain at least 1 molecule of S. Let the min. molecular wt. of Insulin be x. Therefore, 3.4% of x = 32 => 3.4x/100 = 32 => x = 10032/3.4 => x = 941.176 Hence, Option (1) is correct

Insulin constans 3.4% sulphur. The minimum mol. wt. of insulin is-(1) 941.176(2) 944(3) 945.27(4)

Answer»

3.4 % of Sulphur in Insulin means 3.4 g of Sulphur in 100 g of Insulin.

Molar weight of Sulphur (S) = 32 g

Insulin should contain at least 1 molecule of S. Let the min. molecular wt. of Insulin be x.

Therefore, 3.4% of x = 32 => 3.4*x/100 = 32 => x = 100*32/3.4 => x = 941.176

Hence, Option (1) is correct
