Condensation is when a gas becomes a liquid. It happens when a gas, like water vapor, cools down. Matter can exist in three different states: solid, liquid or gas.
When sunlight hits the moon's surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C).
Answer:
The number of mole represented is 2.07 moles
Explanation:
Using the formula
n = m/Mm
n - mole
m - mass
Mm- molar mass
Since the mass is given to be 213g
So lets calculate the molar mass of sodium bromide (NaBr)
The molar mass of Na = 22.99
Br = 79.904
Molar mass = 22.99+79.904
= 102.894g/mol
Using the formula n = m/Mm
n = 213g/ 102.894g/mol
n = 2.07moles
