Explanation:
Cm=247
Cl=35.5
1 mol = 247 + 35.5 = 282.5
So the mass of 5 moles of CmCl3 = 5 x 282.5
Which is 1412.5g
g=grams
The mass of 5 moles of CmCl3 is 1412.5 grams
Answer:
Mass of 5 mole of the compound = 1767.5 g
Explanation:
The compound from the question is known as curium chloride .The element curium is an artificial element and it is also a radioactive chemical element with the symbol Cm . The element has an atomic number of 96.
Curium and chlorine combines to form curium(iii)chloride. The mass of 5 moles of curium chloride can be computed when you get the mass of 1 mole of the compound.
Atomic mass of curium = 247 amu
Atomic mass of chlorine = 35.5 amu
Mass of chlorine in the compound = 35.5 × 3 = 106.5 g
The mass of 1 mole of the compound(CmCl3) = 106.5 + 247 = 353.5 g
Mass of 5 mole of the compound(CmCl3) = 5 × 353.5
Mass of 5 mole of the compound = 1767.5 g
