Answer:
The rock is heavier than water and when put into water it will sink.
Explanation:
Given data:
Mass of rock = 2.7 g
Volume = 1.1 cm³
Type of rock = ?
Solution:
From given data we can calculate the density of rock.
If the density of rock is higher than the density of water it means the rock is heavier than water.
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
d = m/v
d = 2.7 g/ 1.1 cm³
d = 2.5 g/cm³
density of water is 1 g/cm³. The rock is heavier than water and when put into water it will sink.

S is a sphere
P is an infinity
To calculate the molar mass of substance, divide the number of moles by the given mass of substance.
The quantity of a substance is known as a mole. You can measure it in terms of grams, liters, atoms, molecules, or particles.
Use the substance's molar mass to convert between grams and moles. Divide the given mass by the number of moles to convert from moles to molar mass.
Using the formula, Number of moles = Given mass/ molar mass
The molar mass of a substance can be calculated as-
Molar mass = Given mass/number of moles

Answer:
Explanation:
Hello there!
In this case, since the Henry's law is shown below:
Whereas x is the mole fraction, H the Henry's constant and P the pressure. In such a way, we plug in the aforementioned first two to obtain the corresponding pressure:
