Answer:

B.

1-3hours

Explanation:

This is because a diabetic patients have increased blood sugar or glucose concentration. After eating a meal, the blood glucose concentration will be increased as it is been accumulated . Therefore it is best diabetic patient exercise at that hour to reduce it's blood glucose concentration.

**Answer:**

**420 L**

**Explanation:**

Applying Boyle's Law,

PV = P'V'.................... Equation 1

Where P = Initial pressure, P' = Final pressure, V = Initial volume, V' = Final volume.

make V' the subject of the equation

V' = PV/P'.................... Equation 2

From the question,

Given: P = 720 mmHg, V = 350 L, P' = 600 mmHg

Substitute these values into equation 2

V' = (720×350)/600

V' = 252000/600

V' = 420 L

The **molar mass** of **ammonium sulphate** [(NH4)2SO4] is **132.17 g** (option E). Details about **molar mass** can be found below.

<h3>How to calculate molar mass?</h3>

The **molar mass** of a substance can be calculated by adding the **atomic masses** of the elements in the compound.

According to this question, the **atomic** **mass** of **nitrogen** is given as 14.01, hydrogen is 1.01, sulfur is 32.07, and oxygen is 16.00.

The **molar mass** of **ammonium sulphate** is as follows:

[(NH4)2SO4] = [14.01 + 1(4)]2 + 32.07 + 16.00(4)

= 36.02 + 32.07 + 64

= 132.09

Therefore, the **molar mass** of **ammonium** **sulphate** [(NH4)2SO4] is **132.17 g**.
