How many molecules in 0.63 moles

The answer fr the following problem is mentioned below.

Explanation:

Given:

no of moles (n) = 0.63 moles

We know;

no.of molecules at STP condition ()= 6.023 ×10^23

To solve:

no of molecules(N)

We know;

to calculate no of molecules present,the formula is mentioned below as follows:

From the ideal gas equation,

n = N ÷

where,

n = no of moles

N = no of molecules

= no of molecules at STP conditions(Avogadro number)= 6.023 ×10^23 molecules

0.63 = N ÷ 6.023 ×10^23

N = 0.63 × 6.023 × 10^23

N = 3.79449 × 10^23 molecules

Therefore no of molecules present are 3.79449 × 10^23 molecules

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
