So, here you have to look at the periodic table and see what the molar mass of each molecule composing the water compound
![H_2 O](https://tex.z-dn.net/?f=H_2%20O%20)
its two hydrogen atom plus an oxygen molecule, making it about 18g per mol.
That said, looking at the mass, we have to ask ourselves, if a mol of water contains 18g of mass, how many moles do we have in 0.5g of water?
We just do a cross multiplication:
Answer:
B
Step-by-step explanation:
A standard die has numbers = 1,2,3,4,5 and 6
Total outcomes = 6
P = Number of outcomes/Total Outcomes
Even and less than 4 = 1,2,3,4 and 6
P = 5/6

False, An example would be an equilateral triangle with 3 sides of 3 inches, and another with three sides of 5 inches. They will be similar but not congruent because their sides differ. because the sides and volumes differ they will not be congruent.
