What error, if any, would the calculated density of the solid have if the material had a hollow center?

Chemistry
1 answer:
maria [59]3 years ago
3 0

Answer:

3) The calculated density would be high, because the volume would be incorrectly measured low.

Explanation:

Density is defined as mass per unit volume. It means the density is inversely proportional to the volume.

A solid with a hollow center will have high volume due to air inside the hollow area that will lead to low density.

But the error in the calculation of density is that the "density would be high, because the volume would be incorrectly measured low."

Hence, the correct answer is "3)"

Ok heres what i know, one of the reasons why visible light will pass through glass but not through other materials is because the molecules in glass require more energy than average to push electrons from one level to another. Photons in visible light simply do not have enough energy. Only photons of light with shorter wavelengths, such as those that make up ultraviolet light, have the ability to change the electrons in glass. This is why ultraviolet light is unable to pass through glass. Lol im in 6th grade this is all i know ! :)

A tank holds 6.90 m3 of water. What is the volume in ft3? (3.28 ft = 1 m, Remember significant figures, but this answer does not
AleksAgata [21]

Volume of tank = 6.9 m^{3} (given)

Since, 1 m = 3.28 ft

So,  

1 m^{3} = 35.287 ft^{3}

For 6.9 m^{3}:

6.9\times 35.287 ft^{3} = 243.4803 ft^{3}

The significant rule for multiplication, states that the number of significant figures in the answer obtained by multiplication is determined by the value with the lowest number of significant digits.

Since, the minimum number of decimal places in the above multiplication operation is 1 so, the final result must be upto 1 decimal place only.

243.4803 ft^{3} \simeq 243.5 ft^{3}

Hence, volume in ft^{3} is 243.5.
