The density of sugar is 1.6 g/cm3. What is the mass of a sugar cube
with a volume of 5.0 cm3?

8.0 g

Step-by-step explanation:

you have a ratio of 1.6g : 1 cm^3.

x : 5.0?

1.6 * 5.0 = 8

If this is chemistry, you have 2 sig figs. Therefore your answer is 8.0 g

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)
