B. force
C. matter
D. mass

5. The mass of 1 gram:
A. is kept as a standard platinum cylinder in France
B. is .01 kg
C. equals the mass of 1 mL of water at 4°C
D. equals 1 cm³

Answer 1

1.)B 2.)C 3.)A 4.)B 5.)C

Answer 2

1) the basic unit of mass (SI unit) is Kg

2) the amount of matter in an object is known as density, infact the amount of matter in a unit volume is density

3) We can measure the mass with a balance

Burette: for volume

rule : for length

graduated cylinder : for volume

4) Weight is measure of force of gravity on a matter

5) the density of water = 1 g / mL at 4 C

so mass of 1 mL of water will be equal to 1 gram
