1. Round each of the following numbers to four significant figures, and express the result in scientific notation:

vfiekz [6]

The rounding up of the aforementioned number to four significant figures is as follows: 3.002 × 10²

<h3>What are significant figures?</h3>

Significant figures are figures that contribute to the general and overall value of the whole number.

Significant figures or digits are specifically meaningful with respect to the precision of a measurement.

Although, the original number given in this question has 9 significant figures, the number; 300.235800 can be rounded up to four significant figures as follows:

Decimal notation: 300.2
No. of significant figures: 4
No. of decimals: 1
Scientific notation: 3.002 × 10²

Therefore, the rounding up of the aforementioned number to four significant figures is as follows: 3.002 × 10².

How are carbon-based molecules suited for sustaining life?

IrinaVladis [17]

$\huge\fcolorbox{red}{pink}{Answer ♥}$

Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.

Calculate the molar mass of cacl2

kirza4 [7]

Answer:

$\boxed {\boxed {\sf 110.98 \ g/mol}}$

Explanation:

The molar mass is the mass of a substance in grams per mole.

To find it, add the mass of each element in the compound. These masses can be found on the Periodic Table.

The compound given is:

$CaCl_2$

The compound has 1 Ca (calcium) and 2 Cl (chlorine).

Mass of Calcium

The molar mass of calcium is 40.08 g/mol
There is only one atom of Calcium in CaCl₂, so the number above is what we will use.

Mass of Chlorine

The molar mass of chlorine is 35.45 g/mol
There are two atoms of chlorine in CaCl₂, therefore we need to multiply the molar mass by 2.
35.45 * 2= 70.9 g/mol

Molar Mass of CaCl₂

Now, to find the molar mass, add the molar mass of 1 calcium and 2 chlorine.
40.08 g/mol + 70.9 g/mol =110.98 g/mol

The molar mass of CaCl₂ is 110.98 grams per mole.
