Penicillin N is an antibacterial agent that contains 8.92% sulphur by mass.Which could be the molar mass of Penicillin N? a)256g
scoundrel [369]
Answer : Option B) 360 g/mol

Explanation : 
The antibacterial agent Penicillin N contains 8.92% of sulfur by mass. So we have to calculate the molar mass of penicillin N will be as 

i) 256 X 0.0892 = 22.83 g/mol this cannot be the answer as it doesn't shows any sign of sulfur being present even in 1 mole.

ii) 360 X 0.0892 = 32.112 g/mol This is the closest to the molar mass of sulfur which is 32.06 g/mol; this means it contains 1 mole of sulfur.

iii) 390 X 0.0892 = 34.78 g/mol this also fails to prove the answer as correct.

iv) 743 X 0.0892 = 66.27 g/mol This is not even falling in the range of sulfur mole.

Hence we can confirm that the answer is Option B

The use of fertilizers in agriculture has significantly altered several nutrient cycles including:
Lana71 [14]

Answer:

potassium, nitrogen and phosphorous cycle

Explanation:

A fertilizer is a substance which is applied on the plants by farmers to increase the supply of nutrients for the plants. Fertilizers have known to be toxic in many ways such as they alter the potassium, nitrogen and phosphorus cycles. Nitrogen, potassium and phosphorus are present in abundant amounts in the fertilizers. Draining of these fertilizers into rivers and ponds is toxic for the aquatic life. Hence, the use of fertilizers disrupts the natural cycles and is toxic for many aquatic plants and animals.
