Heat is the most important thing in the melting point of rock. Rock, melts when put into<span> 572 degrees Fahrenheit and 1,292 degrees Fahrenheit. Different types of rock may melt at different temperature because in the difference of their material. HOPED THIS HELPS YOU :)</span>
.513mol x (102g/1mol)
Essentially, this is .513 x 102
Which equals: 52.326
But because you can only have 3 significant figures, your answer is:
52.3 grams
I hope this Helps!
Mostly the electrons will determine the reactivity
To determine the empirical formula and the molecular formula of the compound, we assume a basis of the compound of 100 g. We do as follows:
Mass Moles
K 52.10 52.10/39.10 = 1.33 1.33/1.32 ≈ 1
C 15.8 15.8/12 = 1.32 1.32/1.32 ≈ 1
O 32.1 32.1 / 16 = 2.01 2.01/1.32 ≈ 1.5
The empirical formula would most likely be KCO.
The molecular formula would be K2C2O3.
