What is 3.5x10^2 x 8.0x10^-2 in scientific notation

docker41 [41]

Scientific notation is defined as writing a number between 0 to 10 multiplied by a power of 10
3.5 x 10² x 8.0 x 10⁻²
when we solve the equation
answer - 28
to write in scientific notation the decimal point should come after the first digit from the right. to bring the decimal point from after digit 8 to after digit 2, we have to move one decimal place to the left. then we get 2.8, to get the value as 28 we have to multiply 2.8 by 10
therefore answer is
2.8 x 10¹

The mass of a solid substance is 21.1164 g. If the volume of

GuDViN [60]

Answer:

The density of the substance is 1.0611 $\frac{g}{cm^{3} }$

Explanation:

The density of a substance is a characteristic property that matter, whether solids, liquids or gases, has to be compressed in a given space, that is, it allows us to measure the amount of mass in a certain volume of a substance.

Density is expressed as follows:

$density=\frac{mass}{volume}$

In this case:

density: ?
mass: 21.1164 grams
volume: 19.9 cm³

Replacing:

$density=\frac{21.1164 grams}{19.9 cm^{3} }$

density= 1.0611 $\frac{g}{cm^{3} }$

<u><em>The density of the substance is 1.0611 </em></u> $\frac{g}{cm^{3} }$ <u><em></em></u>
