Steven goes to the grocery store and is looking at a winter squash. It has a mass of 1.8 kilograms. How much weight is the winter squash? Answer in grams.
What is Convert 1.8 kilograms to grams. There are 1,000 grams in 1 kilogram. Multiply by 1,000: 1.8 x 1,000 g = 1,800 grams.
There are 1,800 g in the winter squash.

About twenty percent of the National Football League weighs more than 300 pounds. At this weight, their Body Mass Index (BMI) places them at Grade 2 obesity, which is one step below morbid obesity. Determine the mass of a 300 pound (1330 N) football player.

You have a sample of granite with a density of 174.8 lbs/ft3. The density of water is 62.4 lbs/ft3. What is the specific gravity of the granite now?
What is...
Again, the specific gravity is the density of the substance divided by the density of water, so
This shows that the specific gravity does not change when measurements are made in different units, so long as the density of the object and the density of water are in the same units.

You decide you want to carry a boulder home from the beach. It is 30 centimeters on each side, and so has a volume of 27,000 cm3. It is made of granite, which has a typical density of 2.8 g/cm3. How much will this boulder weigh?
What is n this case, you are asked for a mass, not the density. You will need to rearrange the density equation so that you get mass.
d=m/v
By multiplying both sides by volume, the mass will be left alone.
Volume*Density=Mass
Substituting in the values from the problem,
27000cm^3*2.8 g/cm^3=Mass
The result is that the mass is 75,600 grams. That is over 165 pounds!

The rising concern among athletic trainers and health advocates and parents regarding concussions and multiple concussions among high school football players has prompted numerous studies of the effectiveness of protective headgear and the forces and accelerations experienced by players. One study suggested that there is a 50% chance of concussions for impacts rated at 75 g's of acceleration. The average head impact results in 22 to 24 g's of acceleration. If a player's head mass with the helmet is 6.0 kg and considered to be a free body, then what net force would be required to produce an acceleration of 75 g's?

A cup of gold-colored metal beads was measured to have a mass of 425 grams. By water displacement, the volume of the beads was calculated to be 48.0 cm3. Given the following densities, identify the metal.
Gold: 19.3 g/mL
Copper: 8.86 g/mL
Bronze: 9.87 g/mL
What is Copper, 8.86 g/mL?

A golden-colored cube is handed to you. The person wants you to buy it for $100, saying that is a gold nugget. You pull out your old geology text and look up gold in the mineral table, and read that its density is 19.3 g/cm3. You measure the cube and find that it is 2 cm on each side, and weighs 40 g. What is its density? Is it gold? Should you buy it?
What is...
D=m/v
You know the mass (40 g), but the volume is not given. To find the volume, use the formula for the volume of a box
volume = length x width x height.
The volume of the cube is
2cm x 2cm x 2cm = 8cm^3.
The density then is the mass divided by the volume:
D-m/v
The density then is the mass divided by the volume:
Thus the cube is NOT gold, since the density (5.0 g/cm^3) is not the same as gold (19.3g/cm^3). You tell the seller to take a hike. You might even notice that the density of pyrite (a.k.a. fool's gold) is 5.0 g/cm^3. Luckily you are no fool and know about density!
