How many moles contain 1.25x 10^15 molecules carbon dioxide?
IRISSAK [1]
Avagadros number states that 1 mol of any substance is made of 6.022 x 10²³ units.
These units could be atoms that make up an element or molecules that make up a compound. CO₂ is a compound therefore its made of CO₂ molecules.
1 mol of CO₂ contains 6.022 x 10²³ molecules of CO₂
Therefore if  6.022 x 10²³ molecules of CO₂ make up 1 mol 
then 1.25 x 10¹⁵ molecules of CO₂ make up - \frac{1.25 x 10¹⁵}{6.022 x 10²³}
Number of CO₂ moles present - 2.0756 x 10⁻⁹ mol of CO₂

The answer to the problem: 3.6 x 4.639 + 5.831 = _____, written to the correct number of significant digits is:
natka813 [3]

Answer:

3.6 x 4.639 + 5.831 = 2000

Explanation:

In this problem, we need to find the value of 3.6 x 4.639 + 5.831.

Here, 3.6 has 2, 4.639 and 5.831 has 4 significant figures.

We can use BODMAS RULE to find it as follows :

3.6 x 4.639 + 5.831 = (3.6 x 4.639) + 5.831

= 2325.96 + 5.831

in significant gigure,

= 2300 + 5.831

= 2305.831

In one significant figure,

= 2000

Hence, the answer of the problem is 2000.
