Question

2. How many grams are in 2.4 moles of sulfur?

Answer 1

Answer:

mass of sulphur = no of moles * molar mass of sulphur

= 2.4 moles × 32g/mol

=76.8 g

Explanation:

Answer 2

MOLES -

• Significant unit for measuring small entities present such as atoms, molecules, other particles.
• It is defined as $6.022$ × $10^-^2^3$particles present in a substance that can be atoms, molecules, or other particles.
• Moles can be calculated as given weight divide by the molecular weight of the molecule.
• So, weight can be calculated by multiplying the mole with the molecular weight of the compound.
• Weight = Moles × Molecular weight

Moles of sulphur = 2.4

Molecular weight = 32

Weight = 2.4 × 32 = 76.8grams

76.8 grams of sulphur is required to form 2.4 moles.
