Topic 3 – 10 Points

QUESTION:• This is the formula for DENSITY

ANSWER:

•D = M/V

Topic 3 – 20 Points

QUESTION:

• This is the density of water.

ANSWER:

•What is 1 g/mL or 1 g/cm3

Topic 3 – 30 Points

QUESTION:

• If the mass is 400 g and the volume is 200 mL, this is the density.

ANSWER:

•D=M/V which is 400g/200mL= 2 g/mL

Topic 3 – 40 Points

QUESTION:

• This is the density of a piece of styrofoam with a mass of 80 g and a volume of 160 cm3

ANSWER:

•D=m/v = 80g/160 cm3 = 0.5 g/cm3

Topic 3 – 50 Points

QUESTION:

• This is the density of a cube with sides of 2 cm and a mass of 24 g

ANSWER:

• V= sxsxs=2x2x2 cm3=8 cm3

•D = m/v= 24 g/ 8 cm3 = 3 g/ cm3

Topic 4 – 10 Points

QUESTION:

• This is the formula to calculate mass give density and volume.

ANSWER:

•What is m = volume x density

Topic 4 – 20 Points

QUESTION:

• This is the mass of a LITRE of water?

ANSWER:

•What is 1 g/mL x 1000 mL = 1000g or 1kg?

Topic 4 – 30 Points

QUESTION:

• This is the mass of 300 mL of alcohol with a density of 0.7 g/mL.

ANSWER:

•What is m=dxv= 300 mL x 0.7 g/mL = 210 g

Topic 4 – 40 Points

QUESTION:

• This is the mass of a 4 cm per side cube of material with a density of 2.5 g/ cm3

ANSWER:

• What is m=dxv= 2.5 g/ cm3 x (4x4x4) cm3 = 160 g

Topic 4 – 50 Points

QUESTION:

• This is the mass of a litre of gold.

ANSWER:

•What is m=vxd=1000 cm3 x 19.3 g/ cm3

= 19,300 g or 19.3 kg

Topic 5 – 10 Points

QUESTION:

ANSWER:

•What is VOLUME = MASS/DENSITY

Topic 5 – 20 Points

QUESTION:

• What is the volume of 1 kg of water?

ANSWER:

• V = M/D= 1000 g / 1 g/ cm3 = 1000 cm3 or mL or 1 L.
