B. 0.588 mol Ba
C. 68.4 mil Xe
D. 1.57 mol S
Answer:
Mass (m) = Number of moles(n) × Molar mass (M)
A. 6.65 mol W
M (W) = 184 g/mol
n = 6.65mol
mass of W = 6.65 × 184 = 1223.6g
B. 0.588 mol Ba
M(Ba) = 137g/mol
n = 0.588 mol
mass of Ba = 0.588 × 137 = 80.556g
C. 68.4 mol Xe
M(Xe) = 131g/mol
n = 68.4 mol
mass of Xe = 68.4 × 131 = 8960.4g
D. 1.57 mol S
M(S) = 32.1 g/mol
n= 1.57 mol
mass of S = 1.57 × 32.1 = 50.397g
Hope this helps
Molar mass is used to calculate the mass of an elemental sample. For the elements Tungsten (W), Barium (Ba), Xenon (Xe), and Sulphur (S), the masses are 1221.53 grams, 80.7 grams, 8982.216 grams, and 50.35 grams respectively.
The mass of an elemental sample can be calculated by multiplying the number of moles by the molar mass of the element. Molar mass, measured in grams/mole, represents the mass of one mole of a given substance.
