KNO3=40+14+16*3=210 no. of moles=given mass/molarmass. n=m/M= no. of moles=given mass/molar mass =549/210 =2.61
The red is an oxygen molecule. 1 oxygen and 2 hydrogen =h2o or water!
Hello!
When something is a liquid then turns to a gas, this is known as evaporating so we would call it the heat of evaporation or also known as latent heat. Just remember liquid to gas is vapor!
I hope this helped!

The # of equivalents of OH in NaOH is the number of moles of OH divided by its valence.
Molar mass of the NaOH = 40 g/mol
# of moles of NaOH = 40 g/ 40 g/mol = 1 mol
Valence of OH = 1
# Equivalents of OH = 1 /1 = 1 equivalent.
Answer: 1
C would be the best answer because its the most logical one
