What is a 3d subshell? Pls answer as soon as possible.

There are 6.312 moles of CH4 gas in 3.8 x 10²⁴ molecules.

HOW TO CALCULATE NUMBER OF MOLES:

The number of moles of methane gas can be calculated by dividing the number of molecules contained in the gas by Avogadro's number. no. of moles = no. of molecules ÷ 6.02 × 10²³ According to this question, 3.8 x 10²⁴ molecules were given. The number of moles is calculated as follows:no. of moles = 3.8 × 10²⁴ ÷ 6.02 × 10²³no. of moles = 0.6312 × 10¹no. of moles = 6.312moles.

Therefore, there are 6.312 moles of CH4 gas in 3.8 x 10²⁴ molecules.
