Calculate the number of h atoms in 0.185 mole c6h14o.

1.56 × 10²⁴

Step-by-step explanation:

In 1 mole of C₆H₁₄O there are 14 moles of atoms of hydrogen. In 0.185 moles of C₆H₁₄O, the moles of atoms of hydrogen are:

0.185 mol C₆H₁₄O × (14 mol H/1 mol C₆H₁₄O) = 2.59 mol H

In 1 mole of atoms of hydrogen, there are 6.02 × 10²³ atoms of hydrogen (Avogadr's number). In 2.59 moles of atoms of hydrogen, the number of atoms of hydrogen is:

2.59 mol H × (6.02 × 10²³ atoms H/ 1 mol H) = 1.56 × 10²⁴ atoms H

There are 1.56 × 10²⁴ atoms of hydrogen.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
