Answer:
The density of this liquid is 0.320 kg/L
Explanation:
Given:
Volume of the Liquid = 0.820 L
Mass of the liquid = 2.56 kg.
To Find:
The density of the liquid in kg/L
Solution:
Density is the mass occupied by the substance in unit volume. This density is essential determining whether the substance floats or sinks. Greek letter(rho) is used to denote density
The equation of for density is


where m is the mass
v is the volume
On substituting the given values


If I heat a reaction then the rate will increase because the higher the temperature the faster the reaction.

2.2Giga
Explanation:
Given that the number of years = 71years
We need to convert this to seconds;
60s = 1 min
60 min = 1hr
24hr = 1 day
7 days = 1 week
52 weeks = 1yr
71 years x
= 2,232,921,600s
This value is 2.2 x 10⁹s = 2.2Giga
