The number of moles in the 4.30 g of SiH₄ is 1.338 moles.
What are moles?
The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
To calculate the moles
The molar mass of SiH₄ is 32.12 g
The mass of SiH₄ is 43.0 g
[tex]\rm Number\;of \;moles= \dfrac{mass}{molar\;mass}\\\\\rm Number\;of \;moles= \dfrac{43.0}{32.12} = 1.338\; mol[/tex]
Thus, the number of moles in the 4.30 g of SiH₄ is 1.338 moles.
