The weight of a cylinder filled with gas is 30 kg. If the weight of the empty cylinder is 14 kg 80 g find the weight of the gas contained in it.

Answer

To find the weight of the gas contained in the cylinder, we can follow these steps:

### Step 1: Understand the given information
- The weight of the cylinder filled with gas = 30 kg
- The weight of the empty cylinder = 14 kg 80 g

### Step 2: Convert the weight of the empty cylinder to kilograms
We need to convert 14 kg 80 g into kilograms. We know that:
- 1 kg = 1000 g
- Therefore, 80 g = 80/1000 kg = 0.080 kg

Now, we can add this to the weight of the empty cylinder:
- Weight of empty cylinder = 14 kg + 0.080 kg = 14.080 kg

### Step 3: Calculate the weight of the gas
To find the weight of the gas, we subtract the weight of the empty cylinder from the weight of the filled cylinder:
- Weight of gas = Weight of filled cylinder - Weight of empty cylinder
- Weight of gas = 30 kg - 14.080 kg

### Step 4: Perform the subtraction
Now, we perform the subtraction:
- 30.000 kg - 14.080 kg = 15.920 kg

### Conclusion
The weight of the gas contained in the cylinder is **15.920 kg**.
