The density of ether is 0.714 g/ml. What is the mass of 1.45 L of ether?

To find the mass of ether when given its density and volume, you can use the formula:

\[ \text{Mass} = \text{Density} \times \text{Volume} \]

Here's how you can solve it:

1. **Convert the volume to milliliters (ml)**:
Since the density is given in \( \text{g/ml} \) and the volume is given in liters, you need to convert liters to milliliters. There are 1000 milliliters in a liter.

\[ 1.45 \text{ L} = 1.45 \times 1000 \text{ ml} = 1450 \text{ ml} \]

2. **Use the density to find the mass**:
The density of ether is \(0.714 \text{ g/ml}\), and the volume is \(1450 \text{ ml}\).

\[ \text{Mass} = \text{Density} \times \text{Volume} \]
\[ \text{Mass} = 0.714 \text{ g/ml} \times 1450 \text{ ml} \]
\[ \text{Mass} = 1035.3 \text{ g} \]

So, the mass of \(1.45 \text{ L}\) of ether is \(1035.3 \text{ g}\).
