(1) In an experiment for determining the density of water, the following results

Angelina_Jolie [31]

Given parameters:

mass of an empty beaker = 65gm

mass of the beaker and water = 165gm

volume of water = 100cm³

Unknown:

Density of water = ?

Solution:

Density is the mass per unit volume of a substance;

Density = $\frac{mass}{volume}$

To find the mass of the water ;

Mass of water = Mass of beaker and water - mass of an empty beaker

= 165g - 65g

= 100g

So input parameters and solve;

Density = $\frac{100g}{100cm^{3} }$

Density of the water in the beaker = 1g/cm³

100.-gram sample of H2O() at 22.0°C absorbs 8360 joules of heat. What will be the final temperature of the water?

nexus9112 [7]

_Award brainliest if helped!
Assume Specific Heat capacity of water = 4.186 J/g°C
100g sample,
Q=mcΔθ
8360=100(4.186)(Final Temp.-22.0)
Final Temperature ≈41.97°C
