Hey there!
Find molar mass of C₆H₂Cl₄.
C: 6 x 12.01
H: 2 x 1.008
Cl: 4 x 35.45
------------------
215.876g
This is the mass of 1 mole of C₆H₂Cl₄.
Multiply 215.876 by 5.99.
215.876 x 5.99 = 1293
The mass of 5.99 moles of C₆H₂Cl₄ is 1293 grams.
Hope this helps!
Molar mass H₂O = 18.0 g/mol
1 mol ----- 18.0 g
3.5 moles --- ?
Mass ( H₂O) = 3.5 x 18.0 / 1
=> 63.0 g
hope this helps!
Answer:
metamorphic rocks
Explanation:
metamorphic rocks are made from the pressure and heat "metamorphic" comes from greek and it stands for "to change form"
The number at the bottom of each element on the periodic table represents the weight and or atomic weight.
