Answer:
mass of ice is 1.75
Explanation:
Using, the formula given in the question,
m = Q/HΔf.................. Equation 1
Where Q = Heat, m = mass of ice, HΔf = Latent heat of fussion of for ice.
From the question,
Given: Q = 584.5 J, HΔf = 334 J/g
Substitute these values into equation 2
m = 584.5/334
m = 1.75 kg.
Hence the mass of ice without unit is 1.75
5.6 × 10⁻³ g/mol of C₆H₁₂O₆ are in 1. 90 x 10²² molecules.
The mass per unit amount of a certain chemical entity is known as the molar mass (symbol M, SI unit kgmol1). The chemical entity in question should always be identified in accordance with the mole definition.
The number of atoms present in 1 mole of hydrogen is equal to 6.02 × 10²³ known as Avogadro’s number (NA).
The units of molar mass follow its definition; grams per mole. Mathematically, the defining equation of molar mass is
Molar mass = mass/mole = g/mol
180g/mol glucose has = 6.02 × 10²³
x g/mol glucose has = 1.90 × 10 ²²
To find x;

x = 5.6 × 10⁻³ g/mol
Therefore, 5.6 × 10⁻³ g/mol of C₆H₁₂O₆ are in 1. 90 x 10²² molecules.
