It would be potassium chloride or kcl
Answer:
B) 12
Explanation:
Given parameters:
Initial volume = 3L
Initial pressure = 4atm
Final pressure = 6atm
Unknown:
Final volume = ?
Solution:
To solve this problem, we apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".
P₁V₁ = P₂V₂
P and V are pressure and temperature values
1 and 2 are initial and final states.
PV product = 3 x 4 = 12
Answer:
3mL
Explanation:
Density = mass/volume
Give the density of gold as 20g/mL and the mass as 60g
Volume v = ?
Using the above formula
20 = 60/v
Cross multiply
20v = 60
Divide both sides by 20
20v/20 = 60/20
v = 3mL
Therefore the gold of density 20g/mL and mass 60g has a volume of about 3mL
Degree celsius plus 273.15 equals degree kelvin so 77.2 minus 273.15 equals -195.95
