Answer:
16.791 grams
Explanation:
The density formula is:
Rearrange the formula for m, the mass. Multiply both sides of the equation by v.
The mass of the gold nugget can be found by multiplying the density and volume. The density is 19.3 grams per cubic centimeter and the volume is 0.87 cubic centimeters.
Substitute the values into the formula.
Multiply. Note that the cubic centimeters, or cm³ will cancel each other out.
The mass of the gold nugget is 16.791 grams.
Answer:
Chemistry is the study of matter and how it behaves.
The scientific method is the general process by which we learn about the natural universe.
Explanation:
Answer:
2.71×10²⁴ particles
Explanation:
Applying Avogadro's constant
Avogadro's constant states that, The number of specified particles contained in a mole of a substance is equal to 6.02×10²³.
From the question,
If one mole of chlorine contains a particle of 6.02×10²³,
Therefore,
4.5 moles of chlorine will contain a particle of (4.5× 6.02×10²³)
⇒ 27.09×10²³
Hence the number of particle contained in 4.5 moles of chlorine ≈ 2.71×10²⁴ particles
Answer:
hello? are you still here? reply if you are
Deviation of ideal gas is mainly due to interaction between the particles itself, the more they interact with each other, the more it deviates.
HBr deviate more from ideality because of the high electronegativity of bromine. an ideal gas has molecules that preform elastic collision , because bromine is solo electro negative, it may begin to attract slight positive charge of hydrogen atom on other molecules. H2 does not have dipole moment so would act like an ideal gas.
