The density of aluminum is 2.7 g/cm3. What is the density in kilograms per liter? Use appropriate sig figs and no unit

2.7 kg/L

Explanation:

Step 1: Given data

Density of aluminum (d): 2.7 g/cm³

Step 2: Convert "d" for g/cm³ to kg/cm³

We will use the conversion factor 1 kg = 10³ g.

2.7 g/cm³ × (1 kg / 10³ g) = 2.7 × 10⁻³ kg/cm³

Step 3: Convert "d" from kg/cm³ to kg/L

We will use the conversion factor 1 L = 10³ cm³.

2.7 × 10⁻³ kg/cm³ × (10³ cm³/ 1 L) = 2.7 kg/L

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
