You are looking at a flower with 5 petals, 5 sepals, 1 pistil, and 10 stamens. Is this a monocot or a dicot plant? -Need this ASAP! thank you all in advance!!!

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

Final answer:

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.

Explanation:

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.

1. W (Tungsten): It has a molar mass of approximately 183.84 grams/mole, so the mass will be 6.65 moles * 183.84 grams/mole = 1221.53 grams.
2. Ba (Barium): It has a molar mass of approximately 137.33 grams/mole, so the mass will be 0.588 moles * 137.33 grams/mole = 80.7 grams.
3. Xe (Xenon): It has a molar mass of approximately 131.29 grams/mole, so the mass will be 68.4 moles * 131.29 grams/mole = 8982.216 grams.
4. S (Sulphur): It has a molar mass of approximately 32.07 grams/mole, so the mass will be 1.57 moles * 32.07 grams/mole = 50.35 grams.
