Question 34

What is the best metric unit to measure a stack of 10 pennies?

Answer 34

Grams (g)

Question 35

What is the mass of 100 millileters (mL) of water?

Answer 35

100 grams (g) **The density of water is 1g/mL or 1g/cm³** If we know that the density of water is 1g/cm³ then we know that 1 cm³ of water equals 1 mL of water. We can then determine that 1 mL of water has a mass of 1g. Knowing these calcualtions we can then determine that 100mL of water has a mass of 100g.

Question 36

What is the density of water?

Answer 36

The density of water is 1g/cm³ or 1g/mL

Question 37

The density of gold is 19.3 g/cm³ Will gold sink in water?

Answer 37

Yes Water has a density of 1g/cm³ and gold has a density of 19.3g/cm³. If we look at both of these densities we can clearly see that gold is more dense than water and will sink to the bottom.

Question 38

What is the calculation needed to find the density of an object?

Answer 38

To find the density of an object we need to find its mass and divide it by its volume. The answer will be labeled with \_\_\_g/cm³.

Question 39

What would the denisty of an object need to be to float in water?

Answer 39

The objects density needs to be less than 1g/cm³ to float in water.

Question 40

What would the density of an object need to be to sink in water?

Answer 40

The objects density needs to be greater than 1g/cm³

Question 41

What would the density of an object need to be to remain suspended in water?

Answer 41

The objects density would need to be the same as the density of water. It would need to equal 1g/cm³.
