Calculate the mass of a

Chemistry
1 answer:
emmainna [20.7K]2 years ago
6 0

Answer:

10.63 × 10^(-24) g

10.62 × 10^(-27) kg

64 daltons

Explanation:

Formula for sulfur (IV) oxide is; SO2

Now,

Atomic mass of Sulphur is 32 while atomic mass of oxygen is 16.

Thus;atomic mass of SO2 is;

32 + (16 × 2) = 64 amu

Now,

1 mole of a substance has 6.02 × 10^(24) molecules

Therefore mass of 1 molecule of SO2 will yield;

Mass(g) = 64/(6.02 × 10^(24)) = 10.63 × 10^(-24) g

Converting to kg, we have;

10.63 × 10^(-24) ÷ 1000 = 10.62 × 10^(-27) kg

Now, converting to Dalton, we know that;

1kg = 6.022 × 10^(26) amu

Thus; 10.62 × 10^(-27) kg will yield;

(10.62 × 10^(-27) × 6.022 × 10^(26))/1 ≈ 64 amu

Now, from conversion;

1 amu = 1 Dalton.

Thus, 64 amu = 64 daltons

Predict whether each of the following substances would be more soluble in water (polar solvent) or in a hydrocarbon such as hept
vlada-n [284]

Answer:

Vegetable oil will dissolve in heptane

Isopropyl alcohol will dissolve in water

Potassium Bromide will dissolve in water

Explanation:

In chemistry, like dissolves like. This implies that polar substances will dissolve in polar solvents and nonpolar substances will dissolve in nonpolar solvents. This is so because, dissolution of a solute in a solvent involves adequate intermolecular interaction between solute and solvent which isn't possible between a polar and a nonpolar substance.

most radioactive atoms “spontaneously” decay to a more stable form. where does the “additional” energy go once the atoms have de
blsea [12.9K]

When most radioactive atoms “spontaneously” decay to a more stable form the “additional” energy is converted to radiation with the emission of radioactive particles.

<h3>What is radioactivity?</h3>

Radioactivity is the spontaneous decay of the nucleus of an atom with the emission of radiation and nuclear particles.

Elements that spontaneously decay are called radioactive elements.

When these radioactive elements decay, they form more stable isotopes or elements.

The spontaneous decay of atoms of radioactive elements is in order for the nucleus of the atom to become stable and non-radioactive.
