Chemistry Chapter 2 Measurements and Calculations

Front

What is the conversion factor between milliliters and cubic centimeters?

Back

1 mL = 1 cm³, therefore 25 mL = 25 cm³.

Front

What is the formula for calculating density?

Back

Density = mass/volume.

Front

What is the correct measurement for density in g/mL?

Back

1.59 g/mL.

Front

How do you round the measurement 0.0265 g to two significant figures?

Back

0.026 g.

Front

What are the SI base units for time and temperature?

Back

Second (s) for time and Kelvin (K) for temperature.

Front

Define volume in terms of physical space.

Back

Volume is the amount of space an object takes up.

Front

What is the significance of significant figures in measurements?

Back

Significant figures indicate the precision of a measurement.

Front

How do you convert grams to milliliters for a substance with a known density?

Back

Use the formula: Volume (mL) = mass (g) / density (g/mL).

Front

What is the relationship between mass, volume, and density?

Back

Mass is directly proportional to volume when density is constant.

Front

What is the SI unit for mass?

Back

Kilogram (kg).
